Switching to VirtualBox Ubuntu machine only shows some part of screen (rendering problem)

[Florin]

All the times I use the host machine and want to go back to the virtual machine (Ubuntu in full screen), the screen is a combination of host desktop&open_windows and a part (what is dynamic) of the virtual machine screen. See the attached screenshot as an example.

To repaint the screen, I must click on any running program's status bar.

Terminal is in virtualbox machine, everything else is from the Unity host.

And the same bug on another virtual machine, running linux mint.

Does disabling 3D passthrough fix this?

[Florin]

I don't know what 2D passthrough is, but if you're talking about 3D acceleration, it's activated. I would rather have it active as without that I cannot test the Oneiric Ocelot features.

[Florin]

3D, sorry for misspelled word.

[Florin]

I've tested and it really is about 3D. I logged in using Unity 2D (3D still active in VirtualBox machine settings) and now it's rendered correctly. I see you already knew about this bug, is there a solution?

[Leonid Lobachev]

So far, the only workaround is to have composing manager running on your host system, like compiz/unity/aero etc.

[Florin]

I have Compiz running on Natty and also the bug on virtual machines.
