So there are some situations where LyX tries to make a minimal redraw
because ut thinks that the screen is still correct, although Qt actually
wiped it out. We have to find a way to detect these cases.
Could you try the following debug patch? It prints out the code of all
events the GuiWordArea::event() sees. I also removed the cursor blinking
to reduce the number of events.
Could you send me the events that get printed on console at the moment
where the screen turns black?
