Overwatch 2, which seems to get some bizarre mouse issues, though has fewer graphical issues than the Finals
This is 100% Wayland. My mouse became unusable in Debian 13 because Wayland does not provide pointer config like X. They say they won't, it's up to the client.
They do this with keyboard as well. I switch control and caps lock around, but in a game it does not recognize the key map change.
Wayland is probably fine for people who never used X but I find the functional gaps annoying.
Wayland wants to push some hardware configuration to the application which is why you see application developers struggle or give up on Wayland. Imagine a CAD program that needs to deal with every digitizer, tablet, mouse, trackball, or any other low volume PointerDevice - it can't realistically be done.
