Draw class not work correctly for a polygon

[JiriStrnad]

Hi, 

i update API from 4.10 to 4.12. I find problem propably caused WebGL. If create polygon clockwise, all works. If i draw contrariwise, so polygon symbol (simple-fill symbol) is not coloring correctly.

Hi,
I also update API from 4.11 to 4.12. I have some problems like you:
(1) create polygon contrariwise, polygon symbol (simple-fill symbol) is not coloring correctly. 
(2) in some computer(not all) can't draw point,polygon,polyline, and any graphic
(3) in some computer(not all) querytask's result not work if you add them use "graphic+graphicslayer"
(graphics array set to featurelayer source is OK)
(4) if (2)and(3) happened, change view from mapview to sceneview, it work...
(5) but many old computer can't use sceneview(cause webgl?)

I think 4.12 is unstable about graphic... 
can anyone help me?
