Looking forward to a patch for Witcher 3 (DX12). Can't access the glossary menu without crashing the game and SteamOS, since Proton 8.5. I must use Proton-8.17-GE.

It's happening on my Steam Deck and my all AMD PC running Holoiso or Bazzite. No problem when launched from desktop. It seems to be related to gamescope.

Some bugs I'm really in awe and wonder how and why this could ever happen. What is the game doing that this can result in such weird bugs o0
