Using gamescope with Dark Souls 2: Scholar of the First Sin results in a black screen

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

I'm able to repro this on Arch with all backends. what's bizarre is that on SteamOS it seems to work completely fine for me with the DRM backend, so I would've expected the same on Arch while using the same Gamescope package.

Separate from this, it seems to put my external display into a very weird colorspace with the DRM backend where mangohud and the Steam UI are super washed out. Disabling WSI fixes the colorspace issue but not the black screen.

I'm also on Mesa 24.2.4 right now so perhaps I should poke around there a bit for the black screen.

@wantija in ~/.local/share/Steam/steamapps/compatdata/335300/pfx/drive_c/users/steamuser/AppData/Roaming/DarkSoulsII/GraphicsConfig_SOFS.xml try changing:

<Resolution-FullScreenWidth>1280</Resolution-FullScreenWidth>
<Resolution-FullScreenHeight>720</Resolution-FullScreenHeight>

to

<Resolution-FullScreenWidth>1920</Resolution-FullScreenWidth>
<Resolution-FullScreenHeight>1080</Resolution-FullScreenHeight>

for some reason this fixed it on my PC. on my SteamOS device it defaulted to 1920x1080p which is why I did not run into the issue. Window screen width and height are still set to 1280x720
