Bug ID: 527890
Summary: Cursor jumps to its pre-Alt+Tab position on click in
XWayland game
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: xwayland

Reporter: [email protected]
Target Milestone: ---
Since I updated to Plasma 6.8.1 (kwin 6.8.1-2.1), I have an issue while playing
Final Fantasy XIV using XIVLauncher. When I use Hardware cursor in the game
options, my cursor position jumps to a fixed position every time I left/right
click.
That position seems to be the one that was registered before I switched back to
the game window with Alt+tab. This seems to be mitigated by using Software
cursor option in the game.
What I'd expect is the cursor staying where I clicked, and not moving after
alt+tabbing.
STEPS TO REPRODUCE
1. Launch FFXIV with Hardware cursor option enabled.
2. Alt+tab out of the game window.
3. Alt+tab to the game window.
4. Move the cursor to another position.
5. Left/Right click.
OBSERVED RESULT
The cursor jumps back to where it was before I Alt+tabbed back into the game
window.
EXPECTED RESULT
The cursor stays where I clicked.
With a downgrade to kwin 6.8.0-1.1, the issue is not happening anymore.
Upgrading back to kwin 6.8.1-2.1 reintroduced the issue.
The game is running through XWayland. I haven't tried a native Wayland Wine.
I'd be happy to test fixes.
