Description nyanpasu64 2023-02-20 04:41:10 UTC

SUMMARY
When I set "Icons-only Task Manager" grouped tasks to "Shows large window previews", and click a grouped task, arrow keys can select windows not visible and not from the current app.

STEPS TO REPRODUCE
1. In "Icons-only Task Manager Settings", in Behavior tab, set "Clicking grouped task: Shows large window previews" and apply.
2. Open multiple windows under an app, and press Super+Number or click the app's icon. This pops up full-screen previews of the app's windows.
3. Use the arrow keys to navigate between apps.

OBSERVED RESULT
The focus disappears. Pressing Enter opens a window not from the app you clicked.

EXPECTED RESULT
The blue focus rectangle only travels between visible windows, coming from the app you clicked.
