Okay, so this is really weird. I'm working on animation in Flash Ver. 2014.2.0.20, standard action script 3.0, and now suddenly in the last few days there are black splotches that appear behind several symbols. If I select to edit that symbol in Photoshop, the splotches are not there, but they do appear when I run the SWF test preview and in exports. The splotches do not stay a consistent shape or form, either, but vary from frame-to-frame as the animation progresses.
Any idea what causes this or - far more important - how to get rid of it?
1) Flash screen cap - the black splotch for the symbol is circled in red in this image.
2) Photoshop screen cap - the same symbol we just looked at in Flash, but without the black splotch.
