compiz crashed with SIGSEGV in unity::panel::PanelMenuView::UpdateTitleGradientTexture()

[Nick Lib]

Compiz crash after exiting an OpenGL application (the Oculus Rift demo "AaaaaAAaaaAAAaaAAAAaCULUS").

Seems to be reproducible: happened both times I tried.

Running on Utopic, cleanly installed from daily of 06. Oct, with updates installed from one day later.

Mh, I can't reproduce this by using that game... Are you using it in windowed mode?

In any case it would be nice if you could install the unity debug symbols and get a backtrace with gdb from your coredump (see https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages)
