Comment 181 for bug 980519

This is not an issue with 12.04.
I have experienced this consistently in 16.04, 18.04 and 20.04
I have nvidia, so the common theme seems to be nvidia (however, may not even be that).

I have tried in vain to find a fix for the last 4 years and have now learned to live with it (save frequently, etc). It sucks but not enough to go back to Windows

Recently I plugged in a 3rd monitor to my desktop and the issue seems to have increased
