Electrostatic discharges from chairs can interfere with USB and display signals:

"Surprisingly, we have also seen this issue 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."

"This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation."

Design and test is hard /s

A lofty goal but accepting ‘any interference’ is impossible.

That seems to be the general bend of the diagnostic help over reddit, though it seems we may never know for sure. Its been 30 days since Mr. Kanasta's last post.

KaptainKanasta, if you're out there, I know I speak for others who would love to hear if the chair was indeed the culprit. Though if it wasnt the chair and was indeed a malevolent spirit, I fear the worst.
