Bug ID: 58423
           Summary: Flickering in games using dxvk/vkd3d-proton on sway
           Product: Wine
           Version: 10.11
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winewayland
          Assignee: [e-mail]

Games using Vulkan flicker when the compositor supports explicit sync and it is
active after the commit mentioned above.

Disabling explicit sync in sway with `export WLR_RENDER_NO_EXPLICIT_SYNC=1`
makes the game window not flicker even with the bad commit.
