Ultra Key and Lumetri Color leave visual glitches on the export.
I have footage that has Ultra Key effect and Lumetri Color effects applied to it.
When rendered, it shows these black lines flashing on the footage.

After a lot of troubleshooting I narrowed it down to the Ultra Key or Lumetri Color effects on the (facecams out of frame in the screenshot).
I found that swapping the order of these two effects, so instead of:
Ultra Key > Lumetri Color
I changed it to
Lumetri Color > Ultra Key
This seemed to fix it for parts of the video, but not all of it.
