Public bug reported: 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.
