I just added something to the bug reports - I wanted to know if anyone else here has noticed this bug with alpha transparency.

There are video files I've attached, if you could review, you'd see how dramatic it is, anywhere alpha in an image has a slightly green tinge to it - cumulatively it becomes VERY visible. Considering that I often work with 7 or more tracks and layers this is a huge hindrance to me.
