Comment # 2 on bug 1031134 from Bj�rn Lie

I had random crashes too earlier, but the gjs update (1.48.3) we had a while
back fixed that for me.

As you both talk about windows getting reloaded, I assume you are both running
on x still.

Is it reproducible on wayland? (sudo zypper in gnome-session-wayland if
needed).

What hardware / driver is in use here?

If intel gfx, could you both make sure that xf86-video-intel is uninstalled
(I found today that some of our patterns still has that as a recommended
package, even if it's not for the majority of intel gfx out there, will fix
those patterns as soon as possible).

Nouveau has also proven to be unreliable to me on one of my boxes, so that
might be another one to remove if using nvidia hardware.

Failing the both above, please take a look via 
coredumpctl what crash dumps you have for gnome-shell and run coredumpctl gdb
on it with debuginfo packages installed please.
