## Summary
- Closes#8309
- [x] I have followed the instructions in the PR template
`TextEdit` hint text was always aligned to `Align2::LEFT_TOP`, ignoring
the alignment set via `TextEdit::horizontal_align` / `vertical_align`.
This caused the hint text, the cursor, and the typed text to disagree on
alignment: e.g. a centered `TextEdit` showed a left-aligned hint with a
centered cursor.
The hint text atoms now use the widget's `align`, so the hint matches
the input text alignment. The default `align` is still `LEFT_TOP`, so
multi line text edits (and the default styling) are unchanged.
### Root cause
In `crates/egui/src/widgets/text_edit/builder.rs`, the hint-text branch
hardcoded:
```rust
atoms.push_right(atom.atom_align(Align2::LEFT_TOP));
```
while the input-text branch used `.atom_align(self.align)`. The hint
path now uses `align` as well.
### Drive-by: silence `clippy::unnecessary_wraps` in
`egui_kittest::app_kind`
`AppKind::run` returns `Option<egui::Response>`. The `Option` wrap is
required when the `eframe` feature is enabled (the `Eframe` branch
returns `None`), but `clippy::unnecessary_wraps` fires when
`egui_kittest` is built standalone without the `eframe` feature (e.g.
`cargo clippy -p egui_kittest`). The workspace CI run doesn't hit it
because feature unification via `egui_demo_app` enables `eframe`, but
it's a real annoyance for anyone linting the crate on its own. Added a
scoped `#[cfg_attr(not(feature = "eframe"),
expect(clippy::unnecessary_wraps))]` with an explanatory comment.
## Test plan
- [x] Added `textedit_hint_text_should_follow_text_alignment` kittest
regression in `crates/egui_kittest/tests/regression_tests.rs`. It fails
before the fix (`hint_center_x=24.25` vs `edit_center_x=100`) and passes
after.
- [x] `cargo test -p egui`
- [x] `cargo test -p egui_kittest --all-features --test
regression_tests`
- [x] `cargo clippy -p egui_kittest --all-features --test
regression_tests -- -D warnings`
- [x] `RUSTFLAGS="-D warnings" cargo clippy -p egui_kittest --lib`
(pre-existing `unnecessary_wraps` now silenced)
- [x] `cargo clippy -p egui -- -D warnings`
- [x] `cargo fmt --check`

When an image snapshot fails, you get the number of pixels differing by
more than the `threshold` you happened to configure — which doesn't tell
you what threshold *would* have passed. So picking
`SnapshotOptions::threshold` / `failed_pixel_count_threshold` is trial
and error, one CI round-trip per guess.
This measures the failing pixel count at a sweep of thresholds (new
public `THRESHOLD_SWEEP`) and includes it in `SnapshotError::Diff`:
```
'sweep_demo' Image did not match snapshot. Diff: 293, …/sweep_demo.diff.png.
Failing pixels by threshold: 0.0: 1522, 0.1: 1522, 0.2: 293, 0.4: 293, 0.6: 293, 1.0: 293, …
Run `UPDATE_SNAPSHOTS=1 cargo test --all-features` to update the snapshots.
```
The sweep only runs for snapshots that already failed, so passing tests
are unaffected.
Breaking: `SnapshotError::Diff` gained a `failing_pixels_by_threshold`
field.

Adds a `link` feature to eframe to allow disabling links on egui-winit.
The feature is enabled by default so nothing changes for existing users
of eframe.
## Summary
- Add `LayoutJob::clear` to reuse layout settings while rebuilding text.
- Cover preservation of every layout setting.
## Test
- `cargo clippy -p epaint --all-features --all-targets`
- `cargo test -p epaint --all-features`
* [x] I have followed the instructions in the PR template
## Summary
- Add `WidgetText::size` for sizing plain, rich, and layout-job text
uniformly.
- Preserve already-laid-out galleys.
## Test
- `cargo clippy -p egui --all-features --all-targets`
- `cargo test -p egui --all-features`
* [x] I have followed the instructions in the PR template
* Closes https://github.com/emilk/egui/issues/5605
It has been zero by default for a few months now, and I do not wish to
support it. It was always an ugly hack, and it is no longer needed.
Fixes two bugs around tooltips:
- During sizing pass tooltips would render at a different size, at which
point they might overlap the interacted widget causing the hover state
to change and the tooltip to never be shown
- Fix: During sizing pass make the area `interactable: false` so events
pass through
- When hovering close to the boarder of a widget (in the area where
`interact_radius` takes effect), there could be a feedback loop where
the tooltip is shown one frame and hidden the next.
- Fix: Always make tooltips `interactable: false` when they don't have
interactive contents
This PR changes the behavior of `Area::interactable` to it's original
behavior: Now interactions will pass through the area background _and_
it's containing widgets. It worked this way initially but got changed in
#4026

This PR reworks the text input handling logic in eframe's web
integration, primarily in `text_agent.rs`.
It also adds a new `ImeEvent::DeleteSurrounding` variant, along with the
corresponding handling logic in `egui` to support the changes.
## Fix: Samsung Keyboard Cheonjiin issue
This PR fixes a bug reported by @rustbasic when using Samsung Keyboard's
Cheonjiin Korean layout.
Since Samsung Keyboard is only available on Samsung devices, I wasn't
able to verify it myself. The fix is based on @rustbasic's testing and
confirmation.
The root cause is that the layout relies on the preceding text to
correctly handle batchim composition. Previously, the text agent eagerly
cleared the text input after every IME composition, removing the context
too early. This PR makes that cleanup more conservative, preserving the
text when it may still be needed.
My understanding is that this is a quirk specific to Samsung Keyboard:
The IME reports that composition has finished even though it is
effectively still active and the composed text may continue to change.
## Fix: Keystrokes resetting keyboard layout (numpad/symbols/etc.)
Partially fixes#8046.
Previously, keystrokes would cause the on-screen keyboard to switch back
to its primary layout.
One remaining issue is that tapping within the active `TextEdit` to
reposition the cursor still resets the keyboard to its primary layout.
## About text suggestions
I originally planned to include text suggestion support in this PR
because #8068 implemented it.
However, adding text suggestion support would broaden the scope of this
PR, so I think it is better addressed in a separate PR.
For reference, [the reverted
implementation](8a4f70859c)
works fine on Android (Gboard), but not on iOS (iPadOS 17 + SwiftKey).
We had a ton of issues around `TexturesDelta` that weren't properly
applied because we early-out of some function:
* https://github.com/emilk/egui/pull/8313
* https://github.com/emilk/egui/pull/8250
* https://github.com/emilk/egui/pull/8279
This PR changes texture updates, so that we always store them after
taking them out of `FullOutput` and keep the delta around until it's
actually applied (by passing &mut refs and draining instead of
iterating). So even if we add a new early return somewhere, that can't
break texture updates.
It also optimizes `TexturesDelta::append` by dropping any previous
deltas if there's a new `whole` delta or a `free`.
It also adds a debug assert that any `TexturesDelta` is empty when
dropped, as an additional safeguard in case the bug sneaks back in.

* Follow-up to #8296, part of
<https://github.com/emilk/egui/issues/8295>
* [x] I have followed the instructions in the PR template
Stacked on #8296 (base branch), kept as a separate PR so it can be
reverted independently.
The hidden text-agent `<input>` is now inserted as a *sibling of the
canvas* (instead of appended to `document.body`) and positioned with
`offsetLeft`/`offsetTop` instead of `getBoundingClientRect`. Since the
input and the canvas share the same containing block, the input stays
anchored to the canvas top-left corner no matter how the page is
scrolled or how the canvas is embedded.
Consequences:
* Fixes the IME popup position when the host page is scrolled —
`move_to` previously wrote *viewport* coordinates from
`getBoundingClientRect` into document-absolute `left`/`top`.
* Subsumes the mobile Safari virtual-keyboard workaround (it replaced
the flapping `getBoundingClientRect` y with `offsetTop`, which is now
used everywhere), so `is_mobile_safari()` is removed.
* Removes the special-casing of document vs shadow DOM roots — sibling
insertion works uniformly in both.
* The input is `position: absolute`, so it does not participate in
flex/grid layout of the canvas' parent and causes no layout shift.
Caveat: host CSS selectors like `div > canvas:only-child` would no
longer match.
Verified with `cargo clippy -p eframe --target wasm32-unknown-unknown
--all-features` and `cargo fmt --all`.

The `textures_delta` in `AppRunner::logic()` comes from
`TextureManager::take_delta()` via `end_pass()`. Previously, if
`is_visible` was `false`, these deltas would have been dropped and never
applied, so the `TextureManager` state gets out of sync with the
`Renderer`.
That causes https://github.com/emilk/egui/issues/8228: When the app is
loaded in a background tab and the first frame occurs via the
`setTimeout` path prior to the tab becoming visible, it loses the
`ImageDelta` representing the initial creation of the font atlas
texture. When the user then switches to the tab, it panics at
crates/egui-wgpu/src/renderer.rs:669:18 with `Tried to update a texture
that has not been allocated yet` when attempting to update the texture
that the wgpu renderer never saw when it was created.
Testing: To make it load in a background tab, put `data:text/html,<a
href=http://127.0.0.1:8765/>Click</a>` in the address bar and then
middle click the resulting link. On Chrome you also have to hover the
tab preview before switching to the tab to reproduce the issue.

After upgrading to wgpu v30, it requires to drop the `BufferView` return
by `get_mapped_range` before unmap the buffer. Fix it in this pr, making
screenshot event crash no more
- needs #8335
Previously it was impossible to correctly set modifiers via egui
inspection, since that only passes egui::Event and egui::Event had no
way to generally express modifiers.
Now modifiers are passed to egui as a Event and not as a field of
`RawInput`.

## Summary
- [x] I have followed the instructions in the PR template
Fixes the 12 failing `cargo-deny` CI checks on `main` (introduced by
#8289).
### Root cause
`rustybuzz` was flagged as unmaintained by
[RUSTSEC-2026-0206](https://rustsec.org/advisories/RUSTSEC-2026-0206),
reported on 2026-07-12 — after the previous cargo-deny fix (#8300) was
merged on 2026-07-07. The advisory fires on all 12 cargo-deny target
triples.
`rustybuzz` is pulled in transitively via `resvg` → `usvg`, which
`egui_extras` uses for SVG support.
### Why ignore (not fix)?
- `resvg` is pinned at `0.45.1` and cannot be bumped: `0.47` needs
`tiny-skia 0.12`, but `winit 0.30`'s `sctk-adwaita` is stuck on
`tiny-skia 0.11` (see comment in `Cargo.toml` line 128).
- The advisory's recommended replacement is
[`harfrust`](https://github.com/harfbuzz/harfrust), which `resvg` has
not adopted yet.
- This is the same pattern used for the other transitively-unmaintained
advisories already in the ignore list (`ttf-parser` via winit,
`quick-xml` via accesskit/wayland, `bincode`, `yaml-rust`).
### Change
Added `RUSTSEC-2026-0206` to the `[advisories] ignore` list in
`deny.toml` with an explanatory comment.
## Test plan
- [x] `cargo deny check advisories` — passes (`advisories ok`)
- [x] `cargo deny check` — all sections pass (`advisories ok, bans ok,
licenses ok, sources ok`)

## Summary
- Recalculate a menu popup's cached `Area` size when it reopens.
- Preserve cached sizing for continuously open menus and leave tooltips
and general popups unchanged.
- Add a headless regression test covering a wider item added while the
menu is closed.
## Root cause
`Area` keeps its cached size after a menu closes. When that menu
reopened with wider content, the
cached width constrained the new item and caused it to wrap instead of
allowing the popup to grow.
The fix requests the same invisible sizing pass used for a first-open
`Area` whenever a menu was not
open during the previous frame.
## User impact
Menus now expand to fit newly added wider items after reopening.
Existing wrapping, explicit-width,
alignment, screen-constraining, and continuously open menu behavior
remain unchanged.
## Validation
- `cargo test -p egui_kittest --test menu`
- `cargo check -p egui`
- `cargo fmt --all -- --check`
* Closes <https://github.com/emilk/egui/issues/8295>
* [x] I have followed the instructions in the PR template
When an eframe app is embedded in a scrollable host page, the host page
jumped to the top whenever the app booted or grabbed keyboard focus.
Cause: the hidden text-agent `<input>` sat at (0,0) of `<body>` with the
`autofocus` attribute, and all focus calls (text agent and canvas) used
plain `focus()`, so the browser scrolled the focused element into view —
i.e. to the top of the page.
Changes:
* All focus calls in `eframe` web (text agent, canvas, Gboard
blur/refocus workaround) now go through a new `focus_without_scroll()`
helper that uses `focus_with_options` with `preventScroll: true`
(supported by all evergreen browsers).
* The `autofocus` attribute is replaced with an explicit focus call
after DOM insertion — the browser-internal autofocus path always scrolls
the element into view and cannot be prevented by any focus option.
Boot-focus behavior is preserved.
* The text-agent input is initially parked at the canvas origin instead
of (0,0) of the page, so any residual scroll-into-view would target the
canvas rather than the top of the host page. (`move_to` keeps
repositioning it for IME as before.)

Semver-compatible dependency updates (~200 transitive crates in
`Cargo.lock`), plus housekeeping of the version pins in `Cargo.toml`.
## Changes
* Normalize version strings in `[workspace.dependencies]`
(`similar-asserts = "2.0"`, `unicode_names2 = "3.1"`)
* `cargo update`: bump all semver-compatible transitive dependencies
* `itertools` 0.14 → 0.15; the duplicate with puffin's 0.14 /
criterion's 0.13 is now allowed in `deny.toml`
* `rand_core` duplicate (0.6 via phf_generator's rand 0.8, 0.10 via
getrandom 0.4/chacha20) also allowed in `deny.toml` — rand ecosystem is
mid-migration
* `toml` lock moved to 1.1.2 — the old winnow-duplicate blocker is gone
(winit's `toml_edit` now uses winnow 1.x), so the stale comment is
removed
* `wgpu` got a lock-only patch bump 29.0.1 → 29.0.4 (still on the 29.x
line; wgpu 30 intentionally not taken)
## Held back (would fail `cargo deny` with duplicate crates)
* `env_logger` 0.11.8 — newer pulls env_filter 1.x, duplicating the
0.1.x that android_logger needs
* `image` 0.25.6 — needs png 0.18, blocked on resvg
* `smithay-clipboard` 0.7.2 — pulls calloop 0.14, duplicating winit's
0.13
* accesskit platform adapters — newer ones need accesskit_consumer
0.36/0.37, duplicating the 0.35 that kittest 0.4 pins (comments added
for `accesskit_consumer`/`accesskit_winit`)
* wasm-bindgen family kept at 0.2.108 per the sync comment
Majors still blocked (documented in `Cargo.toml`):
`font-types`/`skrifa`/`harfrust` (vello_cpu 0.0.9), `resvg` (winit
