The beta release (7.0.15) has a new castbar.
Possibly another addon? Dominos is reliant upon blizzard for this part.
7.0.14 has proper stealth and shadowdance detection. I don't think I can separate vanish out anymore, though.
Likely a bug
This is probably a bug on my end.

Make sure you have quick paging disabled on bar 1, which activates on shift + number/shift + mousewheel. You may even want to remove the keybindings for it in the blizzard bindings menu.
Its a thing I'll debate adding, as I don't really want Dominos to move everything.
I'd need more detail to figure out this one. Does it happen with just Dominos enabled?
Your probably want to turn off Dominos_ActionSets, which is what does that.
