Screen has start breaking up during Zoom meetings. How to prevent or fix this?

[HughT]

The screen on my laptop computer has started breaking up (as if due to static or interference) at times during Zoom meetings.  This is not happening to other participants, and can disturb them so I have to turn my video off. Does anyone have any suggestions on how to prevent or fix this?

This is my problem too. My picture looks like an Andy Warhol painting. I'm not getting any help from Zoom.
