when the quest action bar shows, either blizzard or dominos... the cast bar shows twice?

thanks

I think this is related to Vehicle Cast Bar.

I saw that Dominos disconnects all base CastingBarFrame events at enabling, but idk what is the use of
_G.CastingBarFrame.ignoreFramePositionManager = true
as this member seems basically not used by wow normal UI.

Otherwise, i think it's possible that entering/leaving vehicule connects/disconects vehicle events to player cast bar on demand. Could explain why the basic cast bar still working when disconnected. Or maybe there is a second hidden cast bar that only manage vehicle casts.

It probably is the separate vehicle one

/framestack on the non-dominos one

and the dominos one I think

/grumbles at blizzard for being inconsistent with how they do quest stuff sometimes.

That's the wrong side of huge teams. There is always someone somewhere that will do bad things others will don't see directly.

I think the simple solution to this is:
_G.PetCastingBarFrame:UnregisterAllEvents()

From reading the code, the pet bar casting bar is only shown if the pet is possessed.
