Public bug reported:
At seemingly random times, but fairly often (a few dozen times during a
normal workday), the mouse freezes temporarily, and a window will start
being dragged around the screen. Sometimes the problem ends when the
mouse becomes unfrozen, but at other times, moving the mouse afterwards
will cause the window to be dragged about the screen. It's as if the
pointer has grabbed a window and won't let go. Hitting Alt+F4 seems to
kill the display manager, temporarily ending the problem when the
display comes back up. After hitting Alt+F4, the windows have all moved
to the top-left workspace, and the top panel does not function normally.
Specifically, double-clicking the top panel no longer unmaximizes a
window. The best way to describe this bug is that it's like having your
computer taken over by a ghost. This problem first appeared when I
upgraded from 11.04 to 11.10. I then did a fresh reinstall of 11.10, but
the problem persists. I thought that the problem might have to do with
the Unity MT Grab Handles, so I disabled them. This appears to have had
no effect. The problem occurs both when using the touchpad and when
using a USB mouse.
