20137	virtualbox manager does not work properly wit 4k monitors on Ubunto 20.04	Lacek		"When installed on a Ubuntu 20.04, virtualbox 6.1.16 runs as empty gray window. The method to fix it is to change scaling in displays settings from 200% to 100% or run it using the ""run_scaled"" script.
Also making the window smaller helps to an extent.

the same problem is related to running virtual machine window. With 200% scaling it has numerous graphical artifacts that prevent normal operation."	defect	new	GUI	VirtualBox 6.1.16				Linux	Linux
