Created attachment 186897 [details] sample project file Stemming from an issue a Reddit user posted today, I've just tested all of the composite wipes available, and found that several of them don't support clips with alpha channel on the top track. Those are: - Circle Wipe - Horizontal/Vertical Barn Door Wipe - Push Down/Left/Right/Up - Rectangular Wipe - Slide Down/Left/Right/Up - Wipe Down/Left/Right/Up ...nevertheless, the "Slide" wipe does work correctly. Perhaps there's something that can be done about it...? I've attached a simple project file to illustrate the problem. Thanks!
