VNC display problem on remotely managed PiHello,To help with digital things around my moms house,

VNC display problem on remotely managed Pi. When i remote connect to a Pi, the chromium tab shows an alternating black screen and a normal but massively distorted/compressed 'normal' screen that is un-usable. The pi is updated, on a stable network connection, adequately powered. Link to image: https://imgur.com/a/fwVcA4H
