Patched COSMIC Comp for Proton/Wayland/XWayland mouse capture issues — looking for testers
I’ve started maintaining an AUR package for a gaming-focused version of COSMIC Comp with additional patches aimed at fixing mouse capture / pointer constraint issues in games.
This is mainly targeted at people using the COSMIC desktop on Wayland who play games, especially XWayland or Proton titles that suffer from problems like:
- broken mouse grabbing
- cursor desync
- incorrect relative mouse movement
- camera spinning or offset issues
Some games that previously had serious issues are now working correctly with these patches.
The fixes are also being worked on upstream, and the related PRs are currently under review:
https://github.com/pop-os/cosmic-comp/pull/2357
Important note: this does not guarantee that all mouse-related issues in all games will be fully resolved. Different games implement pointer handling in very different ways, and some cases may still behave incorrectly. However, this build can serve as a useful reference and testing ground for future upstream development and debugging.
I’d really appreciate it if gamers using COSMIC could give it a try and report their experience, especially with problematic titles. More testing across different games and hardware would help a lot.
The package is available on the AUR: cosmic-comp-gaming
Feedback, bug reports, and game compatibility reports are very welcome.
