Mac OS High Sierra Macbook Pro 2017 15"
Broken: 2.8 Alpha 2
Worked: 2.8 Alpha 2 on WIndows
Short description of error
Grease pencil when set to Stroke snapping does not recognise intentions correctly on any settings and works at what seems like an origin mode. This is specific to 3D drawing. Important note that I tested this workflow on a windows machine and had no issues with snapping strokes to each other from weird angles and from orthographic.
Exact steps for others to reproduce the error
I think it's just broken on mac, I started several projects and it never works. Again on windows works just fine.
