Symptoms

On Fedora 44 / GNOME Wayland / Steam Flatpak, Gothic 1 Remake detects and/or uses incorrect XWayland desktop dimensions when GNOME fractional scaling is enabled on a 4K primary monitor.

With the primary 3840x2160 monitor set to 125% GNOME display scaling, Steam logs report:

Desktop state changed: desktop: { pos: 0, 0 size: 9024,5120 } primary: { pos: 2880,1664 size: 6144,3456 }

In this state, the game appears to enter a runaway high-resolution path in seamless/borderless fullscreen. The in-game resolution selector is locked/greyed out, and performance is extremely poor.

Changing GNOME display scaling for the 4K monitor from 125% to 100% makes Steam report the expected physical primary monitor size:

Desktop state changed: desktop: { pos: 0, 0 size: 5280,2992 } primary: { pos: 1440, 832 size: 3840,2160 }

This fixes the runaway 6144x3456 resolution issue.

Even after that workaround, performance is still lower than expected for the hardware. At 3840x2160 with DLSS set to Balanced in-game and several expensive settings reduced, performance is often around the 50 FPS range outdoors, only briefly exceeding 60 FPS in simpler/indoor scenes.

Current reduced settings tested:

sg.ShadowQuality=1
sg.GlobalIlluminationQuality=1
sg.ReflectionQuality=1
sg.PostProcessQuality=1
sg.EffectsQuality=1
sg.FoliageQuality=1

Other notes:

• VSync disabled.
• Frame limit disabled.
• Textures left at medium/high.
• Other currently played Proton games on this machine do not show this runaway-resolution behavior or comparable performance collapse.

Gamescope observations:

• Host gamescope launched via Steam Flatpak with:

flatpak-spawn --host gamescope -W 3840 -H 2160 -w 3840 -h 2160 -r 144 -f -- %command%

This caused:

Proton: No compat data path?

and host gamescope crashed with SIGSEGV. The coredump was in /usr/bin/gamescope from Fedora (gamescope-3.16.23-1.fc44) with stack traces in NVIDIA/Vulkan pipeline compilation.

• Using the gamescope binary inside the Steam Flatpak extension launched the game:

/usr/lib/extensions/vulkan/gamescope/bin/gamescope

This reports:

gamescope-brokey version 3.16.24

However, it did not solve the in-game seamless/borderless resolution behavior. Windowed mode respected configured resolutions such as 2560x1440, but switching/maximizing/fullscreening the game caused it to return to the incorrect high-resolution path when GNOME fractional scaling was active.

Reproduction

1. Use Fedora 44 with GNOME Wayland.
2. Use Steam Flatpak.
3. Use Proton 11.0 Beta for Gothic 1 Remake.
4. Set a primary 3840x2160 monitor to 125% GNOME display scaling.
5. Start Gothic 1 Remake.
6. Use the game's seamless/borderless fullscreen mode.
7. Observe Steam reporting the primary display as 6144x3456.
8. Observe that the in-game resolution selector is locked/greyed out and the game performs extremely poorly.
9. Set GNOME display scaling for the same monitor to 100%.
10. Restart Steam/game.
11. Observe Steam reporting the primary display as 3840x2160, fixing the runaway-resolution behavior.

Expected behavior:

• The game should not receive or use the inflated 6144x3456 XWayland-scaled desktop size as its fullscreen/borderless render target.
• The resolution selector should expose usable display resolutions.
• Proton/XWayland should provide a sane display mode list or avoid causing the game to lock itself to the GNOME fractional-scaling backing resolution.
