--- Comment #1 from alexandros.frantzis@collabora.com --- We are using a subsurface for the Vulkan contents, but since this is fullscreen the compositor should normally be able to scan it out directly. The Mesa Vulkan WSI also handles dmabuf-feedback and should use the best format/modifiers to accommodate scanout, if the compositor provides such information.
The glitch you see could be caused by any component in the path winewayland -> Mesa (Vulkan Wayland WSI) -> Compositor. Have you tried with a different compositor to see if you can reproduce the behavior?
Also, if you can provide one, a log of the problem with "WAYLAND_DEBUG=1 WINEDEBUG=+timestamp,+pid,+tid,+waylanddrv,+vulkan" could perhaps help shed a bit of light.
