I was recently experimenting with using Gamescope to check whether HDR works on Plasma.
The games run perfectly if I set the compositor resolution (via -W and -H arguments) to a lower value like 1920x1080 (I have a 1440p monitor). But if I were to maximize the compositor window or make it fullscreen (via the Super + F shortcut), the window becomes invisible and I see my desktop. In case of maximizing, the title bar is visible but nothing else.
I have not set --expose-wayland since games don’t even start when I set that. When running gamescope with Steam integration (via the -e argument), steam starts and I am also able to make it fullscreen without any issues, but when I launch a game, I only see the Steam window.
During this time, I can hear the audio from the game, implying that the game is running in the background.
Has anyone else faced this issue and what could be done about this?
FWIW, I am on EndeavourOS with the git version of Gamescope installed from the AUR, though the non-git version does not fare any better. GPU is AMD Radeon with Mesa.
I had this issue when I was using -F fsr, you could try disabling that if you’re using it. I also have to do ENABLE_HDR_WSI=0, since I have that enabled for MPV but setting it to 1 makes Gamescope break.
My current launch options are
ENABLE_HDR_WSI=0 DXVK_HDR=1 gamescope -f -H 2160 --force-grab-cursor --hdr-enabled --hdr-debug-force-output --hdr-itm-enable -- env MANGOHUD=1 %command%. I may also have ENABLE_GAMESCOPE_WSI=1 set as well, you could try that.Using NixOS with Linux 6.8, Plasma 6.1, gamescope-wsi_git, and an RX 7600.
Cool, I tried your launch options and it worked, though I have modified it a bit:
ENABLE_HDR_WSI=0 DXVK_HDR=1 gamescope -f -H 1440 --hdr-enabled --mangoapp -- %command%Everything however had a slight blurriness and I wish FSR worked, however toggling FSR freezes the game. I never used FSR to begin with though.
What is WSI exactly and what patches does this package of gamescope have?
Looking at the Nix package, it seems like it just enables the Meson flag “enable_gamescope_wsi_layer” and adds the package “vulkan-headers” to the build inputs. Looking at the AUR package it uses vulkan-headers but idk what meson flags it uses.
