Hi,

Still seeing this bug, also when unlocking the screen.  Unity version
7.2.0+14.04.20140423-0ubuntu1.2. Is the fix supposed to be released to
Trusty?

This is the stacktrace top from the apport crash report:
?? ()
nux::WindowThread::ComputeQueuedLayout() () from /usr/lib/x86_64-linux-gnu/libnux-4.0.so.0
nux::WindowThread::RenderInterfaceFromForeignCmd(nux::Rect const&) () from /usr/lib/x86_64-linux-gnu/libnux-4.0.so.0

unity::UnityScreen::glPaintOutput(GLScreenPaintAttrib const&, GLMatrix const&, CompRegion const&, CompOutput*, unsigned int) () from /usr/lib/compiz/libunityshell.so

And the full stack trace:
