I'm experiencing this in Ubuntu Groovy 20.10 as well, but I generally only notice it in the gnome top panel. Moving the mouse over the clock or attempting to take a screenshot clears the display error. I've attached photos of my screen and submitted details from `apport- collect`, let me know if I can provide anything else.
