Hi all!

I’ve recently come across an issue with launching games from steam. For now I’ve seen it happen on two games (or rather demos): Crow Country and Sophonce. They launch fine but have some flickering black blocks on the screen that make them unplayable. Here are some images:

This only happens when they go full-screen and on wayland, on X11 works fine. I’ve tried many versions of proton including eggroll variants.

The games work fine when launched with wine without steam in the middle if i do wine <game.exe> . If i do it this way the games detect that I’m running on an ultra-wide screen and play as such but through steam they stay on 16:9 instead.

My system:

Os: Nobara 40
Kernel: 6.8.12-200.fsync.fc40.x86_64
DE: Gnome 46.2
CPU: AMD Ryzen 7 7800X3D (16) @ 5,05 GHz
GPU 1: AMD Radeon RX 7900 XTX
RAM: 32GB

Any help is appreciated,

Thanks!

    I think you are correct assuming it’s an issue with proton not supporting wayland as if i try to use lutris proton still doesn’t work but wine does and so does with gamescope.

    I’m trying to use gamescope now as you and the other comment have mentioned but I’m having the issue with this command, if you could help me:

    gamescope -w 3440 -h 1440 -W 3440 -H 1440 %command%

    It creates a window of the appropriate size but the game is still in 16:9 (Without the black blocks issue, which is already a win, but i’d prefer it to be ultrawide too).

    Thanks for the help!!

    EDIT: Just tried it with Lutris but it seems to also not work even with their setup on proton. So it might be a them thing. For now I’ll just use lutris to play on wine directly.

      The -W and -H are the resolution you want to display at, so you want those to be your monitor’s native resolution. They default to 1280 x 720 if you don’t specify.

      The -w and -h specify what resolution to render at, and are only really useful if using DLSS or FSR for scaling. Skip them if you’re not using that.

        Yes i read that in the documentation but for some unkown reason if i omit either the lowercase or the uppercase the game won’t even start! Only the gamescope instance.

      For some reason I’ve been having issues too, but I started adding this to my launch options in the game properties in Steam and it seems to work for several games. Dunno if this is the same issue as you though, but maybe worth a shot:

      PROTON_USE_WINED3D11=1 %command%

      Also use Wayland.

        Thanks for the input! I tried it but no luck, the black blocks are still there and it still renders on 16:9. Thanks though!!

          Ah, bummer… Can’t you just log in using X11 instead of Wayland for the session when you want to play? Assuming it’s a Wayland issue…

      I don’t have an ultrawide to test, but can you set the correct resolution in the game? Maybe it’s using the settings from previous launches with 16:9.

        Its one of those stylized games where i can not choose resolution, only fullscreen or borderless. And when i choose borderless the screen goes to a small 1080p window.
