I can’t say if this is a bug but I was expecting anything done with layer brush on a layer plus “use current layer offset” not overlapping. But using “Grab” instead of “Dot” mode overlaps.
Just in case this was not intended.
More like a feature not implemented, but I’ll probably simply remove the grab option for Layer.
I guess Grab would be cool if working same like dot. Imagine all Alpha fun. If once it could be possible to combine drag with move to place more properly… Just my two cents.
