overlapping clip is cropping background clip.
i see this thing a lot of time (also on past years), usually i have to use "composite and transform" on overlapping clip to make the bottom clip not cropped. but probably this is a bug and this time i want to open an issue about that.
P.S. this happens only for VIDEO CLIPS (not all formats and not all clips) ... images are not affecting background.
if this is a correct behavior, please close the issue.
