bug report : cross dissolve on videos with opacity mask
I noticed when adding a cross dissolve transition on footage with an opacity mask, it makes the whole area of the footage regardless of the mask, growing from dark to black, until the end of the transition.
the obvious work around is to add key frames to the opacity percentage, but I just want to make sure your aware of this a potential issue.

Another dumb Adobe bug that's been around for many versions (2017+ that I am aware of). I am aware of Cross-Dissolve with a Mask fails much of the time. Not 100% strangely, but like 80 or 90% (depending on the version).
Thank you for the obvious Keyframe Fade-In option. Never even crossed my mind.

If anyone reads this thread, I found how to trigger the issue and a workaround
Green screen, using Ultrakey (no impact)
Using Opacity mask
Using Scale to Frame size as I'm shrinking video a lot in the edit.
Scale to Frame size seems to trigger the issue. Removing it and resizing manually seems to work.
Hope this helps while Adobe looks for a fix!

Same issue here in 14.3.2 in GPU mode (CUDA 2080 RTX) Rendering works in CPU only, very slow of course but works.

Reporting that this is still an ongoing issue! See attached screenshots from a video. The first image shows the graphics fading up from black with the mask visible. The next image shows the mask half revealing the title and the final image shows the title fully revealed. Very frustrating. I was experiencing this problem on and off before updating CC last week too.

Also having this problem doing a simple picture-in-picture. Scaled clip to 80% and added circular mask. I cannot add Cross Dissolve effect without the full size mask appearing as a black circle during the fade up. It doesn't appear when I scrub the timeline, but does appear if I Play or Render.
I tried nesting the clip, assuming it was a rendering order issue (and I need to nest to add a drop shadow), and was surprised that I still could not add a regular, simple fade up & down. The only fix is to use Opacity keyframes.

I also have this issue. Using Cross Dissolve on a clip that includes a mask. The shape of the mask appears as a black shape that fades out as the clip fades in; it appears a mask becomes visible when used in conjunction with cross dissolve. Premiere Pro v 12.1.2
I have a similar problem. I created a layer that I applied a mask to. When I add the cross dissolve a black square appears in the middle of the screen during the transition.
