[Bug 1770731] Re: [nvidia] multimonitor display artifacts
Flickering ghost images may be caused by gnome-shell's damage tracking losing track of where things have been drawn, and it then uses buffer age information incorrectly, leaving junk in only one of the buffers (out of 2 or 3). So every second or third frame contains pixels that shouldn't be there, 20 or 30 times per second. I think the best way to work around it is to drag a window over the flickering area.
