Thanks for the video! That "flash" seems to be the whole screen flickering to black. It can happen if the Wayland backend fails to assign a buffer to the screen for a frame. But it can also happen with monitor connection issues that may be hardware or software (kernel) problems. That's less likely on a laptop but not impossible (I've seen it there too).

Let's assume it's a software bug in Mutter's Wayland backend, but I am out of ideas right now other than using 'Ubuntu on Xorg' as a workaround.
