I presume this doesn't happen with Compiz disabled?

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

comment:4 Changed 5 years ago by Technologov

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.
