Sometimes it will happen with the brush. Some strokes won't work at all, randomly.
I'm using an intuous wacom tablet. Drivers are up to date.
I still keep a copy of photoshop cc 2015 installed in my computer. Mac os X 10.14.2 by the way. And the problem doesn't happen in photoshop cc 2015. Anybody else has encountered this issue?? Thanks.
