@kamp000x If you have the same problem with the apparmor profile disabled, then your problem is not related to apparmor. Then you have a different problem. Maybe your drivers are not compatible.
From my side, I can say that, if the issue is related to apparmor, the E10S issues disappear as soon as FF's apparmor profile is disabled. I've seen/tested that myself.
If your problem is not apparmor related, my patch won't fix it.
