I installed Lubuntu Bionic Desktop 20180425 under VirtualBox on a Windows 10 host. I tried both with and without 3D acceleration enabled. For me, I didn't get any screen corruption.
However...In the past (over a year ago?) I had exactly the same screen corruption you described. There has been recent issues with 3D acceleration in VirtualBox. To the point where I turn it off on most of my VMs. Try turning it off to see if that fixes it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766859 Title: Display corrupted in virtualbox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lubuntu-meta/+bug/1766859/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
