Could this be the same problem that @sauron experienced here?

Mask from file with GL-transitions bug

The mask from file filter has a bug affecting HTML based GL transitions. Using the 2 track method for the transitions, with the softness set above 1%, artifacts are visible at the transition edge in preview and export. I used 50% softness for the attached project. Project illustrating the issue. Mask from file with GL transitions.zip (3.4 MB) This video was done with V 19.02.16. There are no artifacts in the transitions. https://streamable.com/sjc1g
