1904825 - The Select Translations panel flickers when it is painted outside of the window bounds on a RTL build (Ubuntu+Wayland)

Status: NEW

(Firefox :: Translations, defect)

Description

[Daniel Bodea [:danibodea]]

Note

• When the user installs on RTL build launches a minimized window (not maximized) and triggers the ST panel at the left of the window such that the panel will spill out from the window's area, he will notice that the panel will glitch when hovered or interacted with.
• This issue occurs with RTL languages: Persian (فارسی) or Hebrew (עִברִית)

Found in

• Beta v128.0b6

Affected versions

• Nightly v129.0a1
• Beta v128.0b6

Tested platforms

• Affected platforms: Ubuntu+Wayland
• Unaffected platforms: Windows, MacOS, Ubuntu+X11

Steps to reproduce

1. Install RTL language: Persian (فارسی) or Hebrew (עִברִית)
2. Minimize/Restore Down the window (not maximized)
3. Load a webpage in a supported language
4. Select a string of text
5. Open the context menu on the left-side of the window (so that the panel would spill out of the window area)
6. Select the Translate option
7. Hover over the panel using the cursor or attempt to interact with it using keyboard navigation.

Expected result

• The panel displays correctly, no glitches are observed.

Actual result

• The panel flickers/glitches.

Regression range

• Not a recent regression.

Additional notes

• This issue is an edge case because it is specific to Wayland Window Protocol, RTL builds and needs to be opened in a specific way.
