Cross-posted from “Games no longer launching with same gamescope command” by @Blxter@lemmy.zip in !linux_gaming@lemmy.world

My normal command is

gamescope -f -W 2560 -H 1440 -r 144 --force-grab-cursor --mangoapp -- %command%

and games would work just fine. as of yesterday or so games would no longer launch no matter the game. If I remove gamescope it launches fine. I would Like to keep using gamescope but I did some research and apparently there used to be problems with NVIDIA and gamescope. I have used gamescope for many many games with no issues till now

I originally tried on my Endeavour OS install that I have been using for some time but then since I have been meaning to try out cachyos I then tried same thing there and it still does not work with gamescope. I have looked through the proton logs but if im being honest no idea what im looking for. Any help would be appreciated :)
