Brush Mask with Bug (It looks like the noise effect is being applied alone)

[gutoocez]

Hi Community, how are you?
So, it's been a while since my masks have been looking like this,  it looks likew i'm applying a noise effect alone, but it's not. And also appears to have low quality, but in all my already worked files it appears like this.

I don't know if this is a new upgrade and this is something as a default mode.

Anybody has a ideia what's going on? help mee 

Thank u

Have you got any feathering applied?

There can also be masking in Mask Properties, but I don't think that setting is saved, so would appear on a mask by mask basis.

Was the image zoomed at all when you took the screen shot?  I can't really see anything going on other than the feather.  Does that cover it, or do we need to keep looking?
