Here was me thinking it was just nvidia drivers.

"Surprisingly, we have also seen [screen flicker] connected to gas lift
office chairs. When people stand or sit on gas lift chairs, they can
generate an EMI spike which is picked up on the video cables, causing a
loss of sync. If you have users complaining about displays randomly
flickering it could actually be connected to people sitting on gas lift
chairs. Again swapping video cables, especially for ones with magnetic
ferrite ring on the cable, can eliminate this problem."
