Turned on monitor today, notices strange artifacts at the unlock screen. Unlocked and all other windows appear to have artifacts and trouble displaying text and images. Sometimes it's fine and everything is great, maybe the next tab in Firefox has lots of artifacts and the next has none. Konsole, chromium, kcalc and the desktop itself all showed some display corruption of some sort.

I was going to reboot, when I noticed the following in a konsole window I had left open for a few days. I hadn't used the konsole window in over 24 hours and no hardware has changed in that time.
