I literally just unzip the zip file and grease pencil doesn't show any strokes when I draw. I watched some grease 2.0 previews and I'm very interested but it doesn't work for me right now. All settings are on default and I reset settings many times also downloaded both x64 versions to try, same result. My brush color is black nothing shows up on white background. What am I doing wrong?
Edited: Just to clarify somethings here, I'm currently using 2.8 not 2.78 build. I know you have to press D then draw, but it currently doesn't work in the 2.8 version that I've downloaded. My 2.78 grease pencil works just fine.
