I don't expect any official support to resolve this issue, just wondering if anyone else has encountered this or has a fix. I was playing for quite a while using proton, but now the opening title screen isn't loading properly. The 3d dungeon background is visible but the menu isn't displaying. I've seen a few scattered references to this issue around the web but no solutions.

Thanks for reading
