Bug ID: 505298
Summary: Alt+tab not locking mouse to full screen app when
mouse is on secondary screen
Classification: Plasma
Product: kwin
Version First 6.3.5
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: multi-screen
Assignee: kwin-bugs-n...@kde.org
Reporter: jovan.pavlovi...@gmail.com
Target Milestone: ---
SUMMARY
In multi monitor setup (in my case 2 monitors: monitor 1 (left) and monitor 2
(right))
when alt+tab to full screen app but cursor is on different screen (full screen
game on monitor screen 1, mouse on monitor screen 2), mouse will not snap onto
full screen app and will stay on screen 2 until mouse is fully moved to screen
1.
Sometimes when mouse is moved back to screen 1 it will not lock the mouse to
that screen and its possible to move out of full screen window causing next
click to exit out full screen mode.
Video showcase is added to attachments
STEPS TO REPRODUCE
1. Open some other application on monitor 2
2. Open full screen app on monitor 1
3. alt tab and hover mouse over monitor 2 application
4. alt tab back to full screen app
5 . left click (to exit full screen app)
## Continuation for extended bug that is bit more tricky to reproduce
(continuing after step 4)
5. move mouse slightly to screen 1 (had more success if mouse is near the
screens border)
6. click to lock into full screen app
7. move mouse out of screen 1
8. click again (to exit full screen app)
OBSERVED RESULT
Full screen app closes because mouse is on screen 2
EXPECTED RESULT
Mouse should be moved and forced to stay on screen 1
