Discovered this by accident while editing a project.
On video track 2 I applied a transition between two clips. Then split the first clip and applied a text filter to it. When track 2 is played the text bleeds thru into the transition.
On video track 1 I split the first clip and applied a text filter to it. Then applied a transition between the clips. When track 1 is played the text does not bleed thru into the transition.
Seems that if the transition is applied before the filter there's some sort of bug that causes the bleed thru.
Video track 2
Video track 1
Actually, if a split is placed at the beginning of any clip where the transition has been applied before the split, the filter's effect will bleed thru into the transition.
