I edit in PS after LR on most files.
I often put extremely feathered masks on in my files.
Everything was fine until today, after the update.
Now, after saving in PS to go back to LR, the LR preview shows the masks as unfeathered hard lines.
It doesn't look like it in PS, only in LR. And it does export it with the hard lines from LR.
I've tried updating previews, I've toggled and saved with the layers on and off. It's definitley the layers, and it's definitely the way LR is reading them.
