BUG: Dissolve clip with Opacity mask causes flash of one frame of mask at first frame of dissolve.
With a masked and repositioned layer, the mask flashes black in its original position (before repo) on the first frame of the dissolve. Using Opacity keyframes instead is required.

Having the same issue. Layer with mask and a cross-dissolve transition, first frame shows the mask outline in black.
Software renderer does not fix it for me. Opacity animation does.
In a test to reproduce it I also managed to get the mask black to fade rather than just the first frame.
The issue in my case seems to be the use of cross-dissolve to get a quick fade-in effect without a clip on the left side. If I put any clip it works.
Seems like when using a mask the cross-dissolve shows the other clip through the mask, and if no clip is present, you get black.
If there is no mask, it works fine.

Can also confirm that this issue still exists.
Changing the project and export to software rendering and deleting existing rendering files fixed the issue.

Still doing this. Work around is: Preference -> General -> Video Rendering -> Renderer: Software Only

SAME. Super happy to know I'm not crazy. Thanks for the workaround Michael.
Steven Probets commented
Same here! DOES ANYTHING IN THIS SOFTWARE ACTUALLY WORK?!

Also having the same issue. Using warp stabilzer, on a clip in V1 - v2 I have a color matte with an opacity mask and crop with fades on both ends of the clip. FIX YOUR *&^# ADOBE. Premiere 2020 buggy as all heck
Figured a fix around. Get rid of those dissolves. Use the keyframes on opacity and just create your own. I narrowed down the problem to the dissolves.

Can also confirm that I am having the same issue. Really aggravating.
