Some shapes don't draw some of the time in the Editor
I've got some immediate mode code that is roughly:
using(var path = new PolylinePath())
Sometimes the Text and polyline don't render, just leaving me with the discs. The problem occurs when I switch between the Scene view and Game view (while the application is not playing). They only render on the one I had visible during the last domain reload. If I have both tables visible then it flickers between the two depending on where mouse focus is.
It's not 100% reproducible, but seems to happen nearly all the time. I experienced this with a fresh project, with just script in it.
