--- Comment #15 from Bjørn Mork <bjorn at mork.no> ---
No, my desktop environment is not exactly standard. I am using the LXDE 
lightdm and lxsession to fire up WindowMaker as my window manager.  Kind of
prehistoric, I know :)

The hangs always happen when I resize an X client by dragging its frame.  The
client is usually (always?) an xterm.  Don't know if it happens to other types
of clients since I rarely resize them.  But most of the time resizing will not
cause a hang.  If I were to guess, I'd say than only one out of 20-100 such
events ends up hanging the GPU.

I have had no success trying to trigger the bug by repeatedly resizing an
xterm, making me guess that it's not the count but some other factor.  I have
no idea what that could be.  I have not been able to correlate the hangs with
anything else.
