<pre>A fix I've found for the issue seems to be issueing an xrandr brightness
command to each monitor output.
EG: ~$ xrandr --output DP-5 --brightness .99
If brightness is set to 1, the monitor appears to lose some sort of rendering
characteristic, not necessarily brightness - It's like color rendering or gamma
correction change somehow. Simply changing the brightness a modicum seems to
fix the issue.</pre>
