For a while I was using a mac (running macOS) plugged into a dock with
two HDMI screens connected and I was having this problem occasionally.
The mac was clearly thinking the screens had "gone away" because it
would move windows around. I've now switched to a windows laptop, same
dock, same cables, same monitors and the problem has gone away.
