I try autosize and resizing window and selecting Resize from Vortual Screen menu.
Guest additions updated and installed.
Ubuntu 18 host
Win10 64 guest
Tried VBoxSVGA and VBoxVGA
Display mem set to max 256
Any ideas?

I encountered a similar issue a few releases ago. As a workaround, I installed the guest additions from an older release.
