Bug ID: 49298
           Summary: Path of Exile crashes when switching to Vulkan
                    Renderer on RADV. Switching works in proton.
           Product: Wine
           Version: 5.9
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winevulkan
          Assignee: [e-mail]

      Distribution: ---

Path of Exile introduced a new Vulkan renderer in the game.

When switching to Vulkan in-game, the game pauses for a few seconds then
crashes.

If I switch to proton/steam play, the switch to the vulkan renderer in-game, it
works fine and switches as expected.

This leads me to believe this is either a winevulkan or winex11.drv problem,
since those are the two main graphical differences between Standard wine and
Proton. The fact that it runs on proton with RADV also shows that RADV is
likely not the issue.
