Hi I have updated to CC 2018, and when images are showing blocks of varying shades of grey in the layer masks.
I cannot fill a mask with white, and when brushing over the mask, the effect can appear to be brushing out, but return immediately after.
Has anyone else seen this, or does anyone know a cure?
