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)

Out of curiosity, what happens if you try to run gamescope from the terminal to just run anything (not even having proton in the mix).

For example:

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

If this doesn't run, you should get some log lines at least to let you know whats on fire with gamescope.

this loaded fine (pretty cool never even knew I could do this...)

Looking at the logs thought I see two errors even though it ran.

[gamescope] [Error] vulkan: vkGetPhysicalDeviceFormatProperties2 returned zero modifiers for DRM format 0x38344241 (VkResult: 0)
[gamescope] [Error] vulkan: vkGetPhysicalDeviceFormatProperties2 returned zero modifiers for DRM format 0x38344258 (VkResult: 0)

Well sorry. If it works for glxgears there is probably some other weird interaction happening with Steam + Gamescope + Game launching. (you could try to add glxgears as a non steam game to further push the boundaries of if anything will run from steam).

I don't have an nvidia GPU so I couldn't even possibly comment on the state of that situation, but I wish you the best of luck.
