Created attachment 187336 [details] blur issues on clips with alpha channel I just saw that the effects in the blur category aren't capable of correctly handling the alpha channel, in one way or another. To exemplify it, please look at the attached video. I've detected mainly two kinds of problems: 1. Edge handling (straight/premultiplied). 2. Not being able to extend the limits of the clip to accommodate the new pixels generated by the effect. As I could see, all of those effects suffer from the first problem, while most of them also suffer from the second one.
