Title:
External monitor turns off for short period of times / until moving
mouse

Confirmed
Bug description:
In disco; I have this issue where my external monitor (a ThinkVision
P24h-10) connected to my ThinkPad T480s turns off for short times
while actively working on the system. I noticed that if I don't move
my mouse at all while it's off, it stays off.
The T480s is connected to the monitor via USB-C; the monitor provides
DP, USB, and Power over that connection. When the display turns off,
USB devices continue working.
I have attached /sys/debug/dri/0 output from when the monitor was off
(a) vs on (b).
Other related bits:
* This also happens on HDMI, but much less often
* There are no log messages when the display turns on/off in the journal.
