Alpha error on the right side of a ProRes4444 file

I have a transition, its Apple Prores 4444. The right 90 or so pixels are semi transparent when they should be opaque. Its a vertical line, top to bottom, as if a crop was used. 

I just updated to Premiere 25.1.0. Mac OSX Sequioa 15.2

This error doesnt' show up for the designer. I've brought the clip into After Effects 2024.5.0 and DaVinci and i didn't see the error either. 

On the video you can see the semi-transparent pixels over the transparency grid

Uncheck "composite in linear color" may fix this.

YES! Thank you. I've had this problem before, and totally forgot how easy the fix was.
