--- Comment #3 from Werner Almesberger <werner at almesberger.net> ---
I tried stopping and starting the X server a number of times, hoping to get
back the "good" condition I had obtained after disabling TearFree.

After maybe a dozen tries, where at least the first (left) HD was good and the
4K (middle) bad (didn't check the third screen), I ended up with one case where
the first HD is bad but 4K and second HD are good.

So the bug can move to a different screen.
