I am seeing gnome-shell crashes also. However, it usually appears related to OpenGL window resize events as well as xrandr display resolution changes.
Errors in dmesg mention libmutter: [15040.472843] gnome-shell[32127]: segfault at 8 ip 00007f327f29d5d0 sp 00007ffeccf94a38 error 4 in libmutter-1.so.0.0.0[7f327f243000+142000] -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1580605 Title: gnome-shell crashes often Status in gnome-shell package in Ubuntu: Confirmed Bug description: I don't have full stacktrace right now unfortunately but gnome-shell appears to be crashing a lot for me.
