Did you install the guest additions?
Is it the same with 20.04?

Which version of the virtualbox software are you running?

Hi Manfred Hampl,

Currently I am using Virtualbox 6.1.8 (Been using these since 6.1.0) with macos Catalina 10.15.5.
Only Ubuntu 18.04 are having these issues. Screen keep flashing.
Ubuntu version 16.04,19.04 and 20.04 have no issues what so ever.
I think the xorg is very buggy and not been fix.

Then use 20.04. It is LTS and supported until April 2025. 2 years after 18.04 is end of life (EOL)

Can you help with this problem?
