Is this something we could try catching with automated tests?

We are trying to sort out the approach that would let us catch things like this.  In the meantime, I wonder if this is related to bug 1150765 and if the problem goes away if security.sandbox.content.level is set to 0.

Also reported in bug 1151644 (possible dupe)

I don't see this problem on my machine, unless I also set layers.acceleration.disabled preference to true.  See the bug mentioned in comment 3.

Do you still see this with bug 1151644 fixed?

OK. I am closing this bug. It has been probably fixed somewhere else.
