After today’s updates, I am seeing another strange issue: whenever all displays go out due to inactivity and I touch the keyboard or mouse again, the internal display starts to flicker. It looks as if the entire image is shifted by some 25% of its width to one side, then to the other (with the part that would be outside the display area wrapping around to the other end of the display). It flickers back and forth between the two offsets somewhere near the refresh rate. So far I’ve always been able to recover by pressing Ctrl+Alt+F1 to go to a tty, then Ctrl+Alt+F7 to return to the MATE desktop. Not sure if it’s related.
