[XWayland] Rendering stutters in vkcube on Plasma Wayland
If I run vkcube (xwayland) on Plasma Wayland, the rendering stutters and there are some graphical glitches. If I add the overlay (VK_INSTANCE_LAYERS=VK_LAYER_MESA_overlay VK_LAYER_MESA_OVERLAY_CONFIG=position=top-right) even this overlay is flickering and it disappears too. On Plasma x11 it works fine.
Arch Linux Linux 5.3.6 XWayland 1.20.5 AMD GPU with RADV from mesa-git LLVM-svn 10.0
I tried this with Intel and ANV from mesa 19.2 as well, the rendering is smoother and there are less glitches, but not perfect either.
