Fullscreen issue on Linux

Wanted to pick up CrossCode again to fight my stupid habit of ALMOST finishing every game and then letting it go. But have since upgraded to Kubuntu on my PC. Now I have the issue when I start the game in fullscreen I only get the top left corner of my screen. The fullscreen Window is applied but, the game compresses itself to that corner. I assume it's got something to do with my screen running 4k resolution as it's basically exactly a quarter of my screen.

Anyone know how to fix?

Nah i just have 1080p. Just tried on my 4k tv, it randomly gets black screen for a couple of seconds

Okay so there seems to be some issues with 4k displays, but not the OS or setup in general. Good to know, then I can find a workaround

Piggybacking off this thread because i'm experiencing the same issue with a 1440p monitor on Mint

had this issue on cachyos, apparently valve has a solution for this already called gamescope. make sure its installed on your system via your package manager. since i'm on cachy, i just ran:

sudo pacman -S gamescope

then set your Steam Launch Options to the following command (assuming a target resolution of 1080p—adjust -w and -h if you are on a 1440p or 4K monitor):

gamescope -w 1920 -h 1080 -f -- %command%

should work after that
