Symptoms

Fullscreen issues:
When using default settings with DXVK, it renders a frozen white window to the screen (while the game/sounds play and run in the background).
When using PROTON_USE_WINED3D, the fullscreen is zoomed in - by how much depends on the resolution selected in game options. Windowed mode works as it should in both renderers.

Game itself seems to work fine otherwise.
Fullscreening can be substituted with Plasma by forcing the windowed game to span the screen with a WM rule.

Reproduction

Run the game. Always.

Start by reviewing the linked steam-1086860.log and reproducing the fullscreen behavior with DXVK and PROTON_USE_WINED3D on the reported system. Done means the game renders fullscreen correctly without a frozen white window or incorrect zoom, while windowed mode continues to work.
