Hello @twinsonian, please add PROTON_USE_WINED3D=1 %command% to the game's launch options and check if that improves the game's behavior.
Hello @kisak-valve this did not resolve the issue

Has there been any progress on this one? I can get the game to run in software rendering mode, but the video freezes every time I'm on my spell or skill list (basically, any time the game is rendering a menu where the last entry is visible. If the last entry is not visible, as in, producing a scrollbar, then the game remains playable.)

This issue has finally been fixed in the game (see https://github.com/Meridian59/Meridian59/pull/1294). The freeze is still present when the "Preferences" or "Mail" windows are opened, but that's a comparatively less severe issue
