I planned to try a git bisect to hunt this bug down. But this week I tested the 2.2 git branch and first thought that the bug is gone, because I didn't notice the jittering and got no blank screen after an hour or so. However, I left the computer running and when I came back from work I had a blank screen. Then I rebooted and after a while I got the jittering again.
So it looks to be hard to reproduce under certain conditions. I saw no procedure to trigger the bug or make it occur faster. Or did I miss something?
