18886	Virtual screen 2 crashes after update to virtualbox 6.0.10, but only when running ubuntu	haggle		"I usually run ubuntu 18.04 in a virtual box on a Windows 10 host and use two virtual screens, i.e. virtual screen 1 and virtual screen 2. Today I updated my virtualbox to 6.0.10. When I restarted the virtual machine with ubuntu, virtual screen 1 and virtual screen 2 opens as usual, see screen shot here: https://imgur.com/a/owwjNnL

Furthermore, I can move the windows with virtual screen 1 and virtual screen 2 around. However, when I try to go to full screen or to resize the windows, screen 2 closes/crashes. It is then impossible to restart it by choosing view->virtual screen 2 -> enable. 

To see where the problem lies I also installed ubuntu 19.04 and windows 10 in virtual machines. With ubuntu 19.04 I still got the same problem. But with the windows 10 virtual machine everything worked, even if the graphics of window is flickering a couple of seconds before adapting to the new size. What can I do?
