This bug was filed from the Socorro interface and is report bp-f91b1528-a36b-46a0-af27-3dd982161016. ============================================================= I think this is a variation on bug 1309958. That bug fixed the case of some kind of CPOW stuff happening in PScreenManagerChild::SendScreenForBrowser, but I'm also seeing a few crashes involving PScreenManagerChild::SendScreenRefresh(). I assume the patch there is not expected to fix this, too. bp-328182d3-3579-4894-b33e-103832161017

This is pretty similar to the other PScreenManager ones.
