Public bug reported: In a multi-monitor configuration, if the top edge of the RHS monitor is positioned above that of the LHS one, Virtualbox is completely unusuable. The manager is either blank or composed of artefacts, and if starting the VM (eg from the command line) it too is completely corrupted/unusuable.
Aligning the top edges of the monitors resolves this (but in my case one is portrait and it needs to be higher). I am using Xorg but this also exhibits on Wayland. This seems new in 20.04 - I was using the same configuration on 19.10 without issues. So far no other software is affected, only Virtualbox.
