After moving to version 24 I've started to reproduce some of my looks using new tools like the border feature. However I'm having 2 issues. First, the borders are soft compared to using borders made in Photoshop and layered in my multiview. This would actually be fine, it's not so soft that it's a problem, but the second issue is within a multiview some borders are much softer than others, I can't really have a PiP where some borders are clearly blurry compared to others in the same shot. Please see attached screengrabs. Specifically look at the 3 shot, the border on the larger layer is much softer than the 2 smaller layers.
