--- Comment #10 from Peter Eszlari <[email protected]> ---
I compared kwin/x11, kwin/wayland (both 6.4) and mutter/wayland (48) running
inside qemu with virgl (GPU: Intel(R) UHD Graphics 620 (KBL GT2)):

kwin/x11
WebGL Aquarium (1 fish): 60 fps
kwin showfps: 50-60 fps

kwin/x11
WebGL Aquarium (1 fish): 30 fps
kwin showfps: 40-50 fps

mutter/wayland
WebGL Aquarium (1 fish): 50-60 fps


If you want an easy way to reproduce:

Follow this guide:

how to  enable virgl in virt-manager.

I used these two live images for the comparison:
