Games no longer launching with same gamescope command (lemmy.zip)

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 :)

  • GPU: NVIDIA GeForce RTX 3080
  • NVIDIA driver 575.64.05
  • OS: CachyOS x86_64

Edit: I have tried proton versions

  • Experimental
  • Experimental bleeding edge
  • 9.0-4
  • 10.0-2 (beta)
  • proton-CachyOS (native package)

Does it launch when you don't use any commandline arguments? If yes you can then add them back one by one to find which one is making problems.

Yes it launches with no commands. but it does not with just

gamescope -f -W 2560 -H 1440 -r 144 -- %command%

What happens if you just do

gamescope -- %command%
