Cursor locked at the corner (AV1 video warning)

SUMMARY
Please watch the video for more accurate context.
Cursor gets blocked at bottom right corner and can't move it after unlocking the screen.

STEPS TO REPRODUCE
1. Lock the screen.
2. Unlock the screen.

OBSERVED RESULT
Cursor gets locked at the bottom right screen and it goes back to there no matter how much I try to move it from there. I can grow it but it doesn't move.

EXPECTED RESULT
I should be able to freely move my cursor after unlocking the screen.

NOTE: I had to switch to TTY because this bug remains unsolved:

Comment 2 Ángel Navarro 2026-01-10 02:10:13 UTC
This also happens after opening a cursor-grabbing program/game like SuperTux 2.
Comment 3 Ángel Navarro 2026-01-14 08:27:09 UTC
Hey, I can trigger it just by opening Steam. Please help.

This is very likely the same as https://invent.kde.org/plasma/kwin/-/merge_requests/8126#note_1382317
Until beta 2, adding
> gamecontrollerEnabled=false
into kwinrc's [Plugins] group should serve as a workaround.

This just started happening on my laptop yesterday, which is running Plasma built from git-master
