Screen Frozen on
SUMMARY
Plasma Freezes with severe graphical distortions when waking monitors up from
sleep.
I have an AMD Radeon RX 5700 XT with three displayport monitors hooked up to
it. I have these monitors set to sleep after 20 minutes of no activity, the
rest of the system never sleeps/hibernates. When moving the mouse or pressing a
key the monitors will wake up and 9 times out of 10 the screen with freeze /
crash. The monitors are set up in this pattern:
Monitor 2 | Monitor 3
Monitor 1
Monitor 1 (Main) is an Asus 34inch PG348 running at a resolution of 3440x1440
Monitors 2 and 3 are Acer 27inch XF270H with a resolution of 1920x1080
Here is a picture of what the screens do when trying to wake them up:

What you're seeing is the desktop of monitor 3 freaking out on monitor 1. Once
this happens the only way to bring the system back up is to press the reset
button on the front, Ctrl+Alt+f2/f3/etc do nothing.
I tend to use Monitor 3 during the week for work, I have it hooked up to my
work laptop with an hdmi cable and I just change the input to that. This past
week I have left monitor 3 connected to my laptop and not once did I experience
a system lock when waking up the screens. I suspect this has something to do
with plasma handling 2 displayport monitors fine since it doesn't see the 3rd
one that is connected to my laptop via hdmi.
