gnome-shell taking up 100% CPU sometimes

I am currently using GTX660Ti and proprietary driver.
The gnome-shell does not get crazy all the time, but when it does, gnome will be a bit laggy and I will have to "Alt+F2 r" to restart gnome shell, which is very annoying.

Some applications seemed to be triggering this issue, like Android Studio.

OK, how do I debug which part of gnome-shell causing this issue?
Should I use valgrind, or recompile gnome-shell using debug flag?

Have you tried disabling all your gnome-shell extensions? And checked journalctl for anything suspicious when this happens?

I've got exactly the same problem. Looks like it's triggered by qt applications like #mumble. But still didn't find any solution yet.
