I've attached the display to my laptop now, but I haven't been able to
reproduce the bug again.

I'll keep using it and will let you know as soon as I spot this bug once more.

The same problem doesn't seem to happen if I left align the screens, no matter
what position.

Good :-) That helps a lot to narrow down the problem.
