This has been reported by others to the VirtualBox bug reports along with a YouTube video display the effect. I have seen this effect with Unity (3D) running through VirtualBox with 3D acceleration enabled and 128 MB video memory allocated, running on OS X 10.6.8 using ATI Radeon HD 4870. This has also been reported as a problem with GNOME 3.
I am able to login and run Unity (3D), but the display does not match the cursor tracking. Also, the windows do not always display. I can view them if I open Workspaces. When I closed Workspaces, the window "background" remains, but the outline disappears. The visible display is smaller the actual display. I can only see the upper left region. About 25% of the lower display and 25% of the right side are missing.
Unity-2D works fine. OpenGL applications also work, including the test program glxgears with frame rates around 700.
Brian Lee, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-
apport-collect -p xserver-
Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.
Thank you for your understanding.
