[3.14.16] FSR doesn't work with KDE Wayland #1360

Closed SysError99 closed 1 month ago

SysError99 commented 3 months ago

Hardware: AMD Ryzen 5 2500U with AMD Radeon Vega 8 Graphics (VivoBook_ASUS Laptop X505ZA_X505ZA) Software: 6.1.92-1-MANJARO with KDE Plasma 6.0.5 Wayland Gamescope version: 3.14.16

Running Gamescope with FSR enabled caused the screen to flicker in full screen and be broken in windowed mode. Running it in X11 seems to work fine.

Might be related to #1356

This is still replicable up to the master.

The workaround for now seems to be using the SDL backend through --backend=sdl argument

Same issue here using Wayland and nvidia 555. I can't use workaround because it's broken on nvidia.

OMG thank you so much. Ever since switching to NixOS I've had a major problem with gamescope that only manifested whenever I enabled FSR with -F fsr.

Basically the gamescope window would start out semi-transparent at first, then it would quickly become entirely white. Effectively upscaling with FSR was borked. This happened on both KDE Plasma 6 and Hyprland under NixOS. But using --backend sdl fixes it. Maybe this isn't a NixOS-specific issue after all?

I am also having an issue with FSR. I'm running on both desktop (AMD 6800 GPU) Bluefin and steam deck(LCD) Bazzite. Both are using GNOME 46 with Wayland. When using FSR gamescope will launch but the image becomes a white blown out image that does not play properly at all.

Desktop is being ran inside of an Arch distrobox reporting console: gamescope version 3.14.22 . Bazzite is reporting reporting console: gamescope version 3.14.24+. The workaround of --backend=sdl has worked for me as well.

Steam deck works perfectly in gamemode, but looking at other --backend options that would more so be drm or headless. This issue seems to only exist when in desktop/nested mode. Does not matter if fullscreen, boarderless, or windowed. Using other scaling options also fixes the described issue. Both nis and pixel work without issue.

Command: gamescope --backend wayland -w 1920 -h 1080 -W 2560 -H 1440 -F fsr -f -r 144 -- vkcube

I was wondering why the --backend sdl workaround was not working for me. Turns out that the = is very important here, --backend=sdl works just fine. Weird.

On Arch + GNOME with --backend=sdl works also fine. If Game does not open in fullscreen i have to add SDL_VIDEODRIVER=x11
