I have the same issue - drawing top view, camera parallel projection ie effectively 2D. Mac 10.11 (just jumped up from 108.5 - same there) - on a Mac Mini. It is the ‘fill/face’ that blocks the view of the line/guide - delete this and you can see, but each time you draw a line of course you create a new fill/face. Fiddling with OpenGL makes no difference. I’m using ‘Hidden line facestyle. White background.’
This suggests that you are changing the active tag, you shouldn’t do that.
Leave untagged active, draw everything there then only assign tags to groups, components, dimensions etc. Never assign a tag to Raw Geometry.
