After checking this, the watchdog detected system hung and kill the chrome process. Therefore, it caused assertion on child side because it didn't go through normal termination flow.

In my opinion, it is normal behavior to invoke ActorDestroy in child side since chrom process got hang problem. But we don't need to raise assertion in child side, especially in graphic code. Someone has to analyze the call stacks generated from system hang.

I will create another bug to remove the assertion.
