(In reply to Rob Grieves from comment #3) > Any updates? Issue is still present in 6.1.2 Attached a video of the behavior in 6.1.3 Based on feedback from the star citizen Linux user group community this is apparently more noticeable in 32:9, and from my testing that seems to be the case. 16:9 works and the behavior deteriorates as the format gets wider. Windows users do not experience this issue (at least anecdotally, I have asked 10 or so Windows users with 32:9 screens and they have all reported that there were no issues with the cursor behavior). I am not sure which other software presents this issue. I don't see this in hyprland either but similar issues were present in gamescope with the wayland backend. The strangest thing is that the cursor behaves perfectly when in 2D menus (escape menu, main menu) and the 3D "mobiglass" menu. If it wasn't for the fact that the issue doesn't appear to happen in hyprland or Windows I would chalk it up to a developer bug. A last thing of note is that if I move the cursor very slowly the issue goes away. (In reply to Daniel Ellis from comment #5) > (In reply to Rob Grieves from comment #3) > > Any updates?

Thanks Daniel. I'm on 16:9 4K and it's bad. Like can't use inventory or intractable screens bad. There's a lot of discussion about it in this gamescope bug which might help. Sounds like same root cause but symptoms present differently in gamescope vs kwin. https://github.com/ValveSoftware/gamescope/issues/1319#issuecomment-2238844002 |
