Bug description:
I am using Ubuntu 18.04 with gnome shell on Wayland.
From time to time, maybe every one or two hours, the desktop becomes
white for a fraction of second. I guess it is just one frame (1/60 of
second). It looks like a full filled rectangle of white color but it
is so fast I cannot verify to be sure (the only solution I'm thinking
of would be to have a fast recording camera pointed to my display).
I did not experience that problem on Ubuntu 17.10 with Wayland.
