[Lee Salzman [:lsalzman]]

If you look in the log for the call stack below, there is an X error generated by some gdk_x11 call which then causes a trap.

Comment 2

[Robert Mader [:rmader]]

This should be reproducible via:

MOZ_X11_EGL=1 ./mach talos-test --enable-webrender --enable-fission --suite sessionrestore-many-windows

Comment 3

[Robert Mader [:rmader]]

Reverting bug 1684194 fixes this issue, so looks like this has something to do with RenderCompositorEGL.

FTR, I tried again if I can reproduce the issue locally, but it does not reproduce on my mashine.

Moving this to bug 788319.
