In 25 april version, changing to tty and back (Ctrl+Alt F1 and the back with Ctr+Alt F7) display correctly.

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.

I had that same problem in the past and that solved it, and now 3d acceleration was disabled.
However, when te system is installed the problem doesn't occour (after installing Bionic and I'm using daily a 17.10).
It also doesn't happen when I use an already existed VM, and boot from it . But with a knew one it happens, ita happened with Bionica Daily 25.1 too.

The workaround of switching to tty and then back to x still works.

My main Windows 10 computer on VirtualBox 5.1.34 works fine.

I tried on my laptop:
host OS = Windows 10 Pro
VirtualBox: 5.2.8

Works fine with and without 3D acceleration. Full screen window, and small window.

I tried on another desktop:
host OS = Lubuntu 18.04 daily
Computer = Intel Celeron N3450, 4 gig ram
VirtualBox : 5.2.10 from the VirtualBox web site (not the one from the Ubuntu repo).

I got the screen corruption.

But...if I maximize (hit the "+" in the top right of the vm window) and reset the vm to reboot it will sometimes work on the next try. Vice versa, hitting the "+" sign to put it back to windowed mode and resetting also sometimes fixes it on the next try. Changing the size may do nothing, it may just may be random after a reboot.

It's failing inconsistently. It can definitely fail with 3D acceleration both enabled and disabled under an Ubuntu Host. But I couldn't duplicate the problem with a Windows 10 host.

It's weird. I can no longer duplicate the screen corruption on my Lubuntu 18.04 system now. No matter what settings I use, it always works fine.

mberna's solution here is what worked for me on an Ubuntu 18.04 host with whatever is the current Lubuntu 18.04 desktop amd64 ISO:

1. disabling nested paging (system → acceleration → enable nested paging checkbox)
2. increasing the video memory to 128 mb (display → video memory slider)

After installation you can re-enable nested paging.

Press Esc in the language selection menu and select nomodeset in the "Other Options" menu. This somehow works for me.

And yes, just like what Jb said, sometimes it just works without any issue. The issue is very hard to reproduce once you solved it, no matter what settings you use. Now the ISO boots fine with 64 MB of video memory, nested paging simulation and 3D acceleration.

Status changed to 'Confirmed' because the bug affects multiple users.

Changed in lubuntu-meta (Ubuntu):
status: New → Confirmed

It affects me as well, with the host being openSUSE Leap 15.0 with Intel graphics. (Guest is the aforementioned Lubuntu 18.04.) The workaround to switch TTYs (via right Ctrl+F1/F7) works.
