Question

Feathered Mask edges showing as extreme banding in mask view mode

Since the most recent PS 26 - 27.9.1- possibly a little earlier, Mask edges in mask view mode are extremely banded, no matter how much you feather and even whilst working in 16 bit. It seems to be more of a view-mode issue rather than actually showing as banding on the image - however it makes masking difficult to work with.

    Not seeing this myself, but there have been some cases here of excessive banding in grayscale images - which is what a mask is.

    This appears to be a GPU-related bug.

    Post the full Help > System Info, and others seeing the same thing should also post System Info. This should give the engineers something to work with and hopefully reproduce.
