What desktop environment, distro? What steam launch options are you using?(gamescope -- %command%)

[revulent]

plasma, fedora 41.

gamescope -f --hdr-enabled -W 3840 -H 2160 -r 240

playing with the command lines though doesn't seem to matter

but it seems to be working now? I'm not sure what happened
