shows the flickering in the video

SUMMARY
Games that use vulkan natively instead of directx through DXVK/VkD3D experience a flicker when entering/exiting fullscreen and when a OSD or notification appears over it.

Attached video will show example of what occurs.


STEPS TO REPRODUCE
1. Open vulkan title  (e.g. PEAK, DOOM Eternal, BeamNG.drive)
2. Use the mute/unmute audio shortcuts or have a notification appear over the fullscreen window

OBSERVED RESULT
Black flicker over the fullscreen window when OSD/notification appears over it.

EXPECTED RESULT
OSD/notification would appear without causing flickering.
