I presume this doesn't happen with Compiz disabled?

Interestingly, #9828 seems to be the same in reverse.

comment:4 by Technologov, 13 years ago

The bug is not in reverse -- it is the same bug... Basically Bug #9828 says that mouse becomes invisible when moved on top 3D accelerated surface. My tests prove this is the case.

Steps: Enabled 3D acceleration and start "glxgears". (RHEL 6 guest)

If mouse integration is ON = mouse is visible. (OK)

If mouse integration is OFF = mouse is invisible. (BUG !! - happens when moving on top of 3D surface)

I experienced today this bug on Mac OS X (as host) and Ubuntu 16.04 with Unity (as guest) after enabling 3D Acceleration in the VM's settings.

I also successfully used the workaround mentioned in this link: Namely, disable and then reenable Mouse Integration. The fix survives even if I shut down the virtual machine and start it again from VirtualBox.

Given I'm using Unity, I guess the whole VM image is a 3D accelerated surface, so my data still fits @Technologov's "mouse becomes invisible when moved on top 3D accelerated surface".

What I did: I created the image using Vagrant's ubuntu/xenial64 box, enabling the GUI, apt-get install ubuntu-desktop, and restarting. The mouse worked fine. Then I enabled 3D Acceleration and installed/updated the Virtualbox guest additions, and the mouse stopped working; I'm not confident exactly what was needed.

This is a known issue with the way we handle 3D currently. It is one of many little issues which do not make sense to address individually as we should rather spend time, if and when we find enough of it, redoing the whole subsystem.
