You've discovered non-deterministic binaries! :-)
Is it possible it is an obsolete add-on causing the problem? I can't
remember if you said safe-mode worked or not.
What about a different user? Maybe it is interacting with some other
configuration you have in your environment.
What if you try a different desktop environment? XFCE? Mate?
Cinnamon? LXDE? Gnome is pretty heavy weight, as is KDE, but you
could also try them.
There must be a difference.
