Desperatly would like to see the bug fixed with transparent .png image sequences where you see the poster image in the background when swiping through image sequence. Is this going to be fixed any time soon???
I guess what you call a bug, they call that "as designed", since that "first image" of a png overlay sequence is no more than the flattened background you have when no interaction started, and that is not removed when this particular interaction starts. From here, i tend to put no first image and have my sequence auto start (even with a delay if necessary).
