--- Comment #4 from Werner Almesberger <werner at almesberger.net> ---
I cycled the X server some more: in a series of 25 tries with TearFree off, in
24 the 4K screen had the problem, once the left HD screen, never the right HD
screen, never less or more than one screen.

I then turned TearFree on again and tried some more. After 19 tries with the
problem on the 4K screen, I again had one case where the first HD screen was
affected.

So TearFree may have nothing to do with it after all.

However, in all these tries, I was never able to get all three screens to work
properly, like they did when I disabled TearFree the very first time.
