There are some white artifacts around the cubase text for some reason. They’re so tiny you don’t even see them in the thumbnail you posted, but when zoomed fully you can see them. I can get rid of the most obvious ones myself with some work, but some of them are covering the red shade etc, and hard to mask.
Any idea if they’re easier for you to get rid of using the original file? (I was using the fully black 1920x1200, not checked the others yet.)
