At one point After Effects started to have this background image on all compositions (existing old files to new ones) in 640x1136 dimension.
Problem is, I'm a UI designer and 80% of my works are in that dimension.
Funny thing is, if the dimension is a pixel off, then the transparency returns back again. BTW, that background image with shoes is something one of the projects that I'm working on.
All of my old compositions now have those shoes flashing whenever there's supposed to be transparency and it's just driving me crazy.
I need to get this thing fixed ASAP. please help!
