It looks like it is related to the positions of the two displays to each other. I normally like the internal display to be below the external one. By default it tries to layout the display next to each other. When adding the external display I can see the wallpaper twice on the external display. On the left the small one that should probably be shown on the internal display and on the right side the large one that should normally be used for the external display. After a few moments the large one is shown on the exeternal display and the internal display has a black background. When I switch to the virtual desktop on the right side I do see the small wallpaper in the top left corner surrounded by the flickering.
