RotoBrush 2 Selection Expansion issue
Whenever I try to use Rotobrush 2, the selection constantly expands after a few frames until it selects the whoel screen.


I tried 4 different videos and reinstalled After Effects, but it behaves the same as well.
Furthermore, it also sometimes yield the error message : Unkown Exception too.
Any help on why this tool is behaving this way would help a lot.
