[Bug 1246509] [NEW] Computer Freezes when Fullscreening Application (Snapping to Fullscreen)

 

Public bug reported:

I'm running Ubuntu 13.10, and about twice a day, when I try to full-
screen an application, Unity/Ubuntu partially crashes.

I am trying to full screen the application by dragging the window to the
top of the screen, something I do many, many times a day.

I expect for the animation to finish, and the window that I'm dragging
to pop into "full-screen" mode, where it takes the entire window.

Instead, the animation hangs half-way before I release the mouse (while
I'm still dragging), and the computer partially hangs.  The mouse still
will move, but doesn't have any effect on the desktop.  I _am_ able to
Control-alt [1-6] to get into an alternative terminal, and I can execute
most commands, however trying to logout of Ubuntu from the terminal or
kill Unity has no effect, the graphics remain frozen on the screen.

I don't know any more debugging actions to take, I'd be happy to submit
more if someone had an idea of which diagnostics/logs I should run or
look at.
