After a seemingly random amount of time, two players see each others video either freeze or go black and all sound from the other is gone. Other players can still hear and see the two. It seems to be the same two players most of the time, but not always. And it's possible for more than one pair of these drops to happen.One player can be the one with the issue the most one day and be bug free another day. Reloading is the only known workaround for now.Which isn't exactly satisfactory - especially since this can happen within a minute after logging back in if unlucky. Everyone involved is using either Chrome or Firefox and is generally able to use RTC successfully.Internet connections are stable and fast.
