I have already reported this as a bug here but I’m unsure if its a problem with Kwin or just my OS, hardware, missing a library or something so I’m posting here to see if anyone else has the same issue and try to understand what is causing this.
On Wayland, whenever I try to enable fullscreen for any game (doesn’t matter if it runs natively or under wine/proton, or which graphics API it uses), the window just becomes invisible and I can’t interact with it, forcing me to kill the process. On X11 it works as expected.
This only happens for games. I thought it had something to do with Xwayland but any other application works fine.
I am running with Polonium (tiling WM script) and a custom font DPI setting. I don’t think these affect anything though.
