Commen= t # 4 on bug 10600= 6 from Joel Sass 
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 renderi=
ng
characteristic, not necessarily brightness - It's like color rendering or g=
amma
correction change somehow. Simply changing the brightness a modicum seems to
fix the issue.
