--- Comment #20 from Henrik Fehlauer <rk...@lab12.net> ---
I don't think Spectacle is doing anything wrong per se, as it's working fine on
a bunch of systems. Still, we might be hitting a code path in Qt, X, or the
graphics driver which some systems are unhappy with. (Note that in Spectacle
only the fullscreen rectangular selection tool is written in QML, which makes
use of OpenGL acceleration.)
It's a bit hard to debug this without being able to reproduce, but at least we
can try to narrow down the nature of the problem. Could you record a video of
the hang and the events leading to it? As in the comments above "hanging" is
associated with multiple different issues, what are you doing exactly in your
case? Also, having a look at the memory and CPU usage of all processes on the
system during the hang would be great, maybe on a console or via ssh?.

Any chance you could start Spectacle through "gdb" and interrupt it with Ctrl-C
while the hang occurs? Would GDB's remote debugging help, assuming the network
stack is still working?

Please try to reproduce running a simpler DE than Plasma, e.g. IceWM or TWM.

Did you try setting it to "XRender"?
One more thing to check is that you are indeed running only a single Spectacle
process (see Bug 386629 I just added some comments to).
