ProRes 4444 Alpha bug
I ran into a serious little issue:
Have a ProRes video, and it‘s overplayed by a graphical render from afx, being prores4444 alpha. It‘s fine by itself, but when there‘s a dissolve applied, AND a mask in the opacity settings, suddenly a strange black box appears during the dissolve where the video should be. This happens on the Mac Pro 2013 with D700 under OpenCL and Metal. If I switch to software, the bug disappears, but then the alpha element has a small black bar around all edges.
Please look into that!

Hello, Would you have the original ProRes file ?
