Comment 71 for bug 570151

I beg to differ on the "fixed in Oneiric". I am seeing the issue in Precise Penguin on another machine of mine. Although the behavior is not exactly the same, it is very similar.

The Precise Penguin machine is setup with a Windows XP Virtual Machine using Virtualbox and also has dual monitors. The issue occurs when multiple programs are open, namely Powerpoint and GoToMeeting. It almost always occurs when the user moves a window from one monitor to the next. The mouse blinks rapidly, but is not "stuck". However, it is very difficult to see and control. When this issue occurs, Xorg is spiked.

To resolve the issue, I use a remote desktop client from another computer to access the Virtual Machine (Windows XP). I close all programs she has open. I don't have any issues seeing or controlling the mouse from the remote session. Once I have closed all programs, she is able to see and control the mouse as normal. I have her shut down and restart both the VM and the physical box.

Given the issues I am seeing, I would not consider this fixed in Oneric.
