Gio External Monitor Glitchy Output Issue

This is an intermittent issue, happens seemingly randomly. One of the external monitors on a DVI Gio has been getting weirdly distorted and glitchy appearing. 

Sometimes it's localized just to one tab as in the video, or the full display like the images linked

Doing anything that will refresh the tabs in the display will fix the issue - video linked below - hitting go in this instance cleaned it up. 

Have done a deep clear at recommendation of someone else and plenty of restarts with touring through venues but issue persisting

Curious if anyone else has had this issue. Not show stopping because it immediately comes right, just a little worrying!

Gio is running 3.0.2 Build 6

Screens are HP Compaq L2206tm
