After Update to 6.1.16: Black screen after booting Ubuntu in fullscreen

Description
I use Ubuntu 18.04.5 LTS (64-bit) as guest and Windows 10 as host and always do all VirtualBox-, Ubuntu and Windows-updates available.
I boot into fullscreen mode. Since Upgrading to 6.1.16 after booting the screen is black. The boot screen-sequence (purple screen with Ubuntu logo and some text output) appears. But once the desktop should appear the entire display is black. Not the entire: At the bottom the VirtualBox-toolbar is available and accessable. Once I use it to switch to window-mode the screen refreshes and I can see and use the desktop. After that I'm able to re-activate the fullscreen mode and fullscreen works as expected.
If I boot in window-mode then the desktop is shown as expected. I also tried to boot without 3D acc. but the screen is also black without this setting.

Host-OS: Windows 10 Host-graphics: GeForce RTX 2060, set NVIDIA 3D to use GeForce for virtualboxvm.exe instead of internal graphics of the laptop.

#19535 seems to be the same. I was wondering if this is the same because I experience this only since upgrade to 6.1.16

Another hint: In #19535 is reported that it occurs after login. If I change from fullscreen to window mode and back again during the guest's boot sequence the screen is NOT black after login. It seems that deactivating and activating the fullscreen mode works as a workaround regardsless the current screens resolution and state of the guest's boot sequence.

What if pressing "host key" (normally right CTRL) + F2 and then "host key"+F1 again instead of deactivating and then activating full screen mode?
This looks like yet another case like #19873, #19906, #19535...
