When i use brush for undo the radius action, this don't back
how it was before in a perfect way, it comes with a
imperfection/distortion on it. In Photoshop CC 2015.v16.0 it works like should be.
Looks like it retains a small amount of radius on 2015.5 after erasing it.
Watch the short video (in HD for better biew), for understand what i mean:
Please can someone try it and tell me if happen the same? Thx.
