Thanks.
Sounds like it might end up being the same problem as bug 1748871. Even
though the appearance of the flicker seems different.

Title:
Flickering screen with ultra-wide monitor in Wayland mode
Status in mutter package in Ubuntu:
New
Bug description:
1. leave computer until gnome-shell blanks the screen (monitor goes to sleep)
2. clear GDM screen by swiping up.
There is a video flicker now when I interact with computer.
Usually small, but can cover many different UI elements.
This does not happen if I use the X backend instead of wayland.
