I turned off extensions using the Tweaks app for Gnome but the problem still occurs, whether I turn off the monitor or let it enter standby. It does not occur, however, if I connect the monitor through HDMI (I normally use 2 monitors--one through DisplayPort and one through Thunderbolt 3 to DisplayPort, both of which cause the problem). Intel HD Graphics 630 (Kaby Lake GT2) driver=i915 according to lshw -c display
