Skyrim special edition hangs for me on the main menu with a Radeon R9 Fury using RADV. The corresponding DXVK issue can be found here https://github.com/doitsujin/dxvk/issues/927 The issue occurs using Mesa 18.3.3(LLVM 7.0.1), Mesa 19.0.0~rc4(LLVM 8), and Mesa 19.0.0~rc4(LLVM 9-svn). The build of 18.3.3(LLVM 7.0.1) came from the debian sid repositories, the 19.0.0~rc4(LLVM 8) was built by me linking against debian sid's libllvm8 and then 19.0.0~rc4(LLVM 9-svn) was built entirely from scratch.
So is this an actual hang of the GPU or just a freeze for the game? (i.e. does it need a reboot to do anything again or can you just close the game?) Reading the DXVK bug I'm wondering which of the two it is.
Yeah, apparently I didn't make that very clear. It is a GAME hang. As in I have to forcibly kill the game from htop but it is not a full system hang.
It turns out this issue only occurs under XWayland and NOT under X.Org however I'm not sure if it's actually a mesa bug with XWayland or an XWayland bug directly.
