Draw.Line in ImmediateModeShapeDrawer not shown on Android/iOS

Hello, Freya, and thanks for the amazing plugin!

I encountered that a straight line drawn with a simple Draw.Line() is showing good in Unity edit/play modes, but is not been drawn on mobile device. I tried either Android and iPhone.

I found a similar post here https://shapes.userecho.com/en/communities/1/topics/192-immediate-mode-drawline-not-appearing-in-standalone-build and as recommended there I turned off GPU instancing for Immediate Mode in Shapes Settings. 

This workaround works for me (at least I already tested on iPhone).

I still decided to post a message here just to let you know.

My code is pretty simple:

public class DrawController : ImmediateModeShapeDrawer{

...

public override void DrawShapes( Camera cam ) 

{ if( cam != this.cam ) return;
using( Draw.Command( cam ) ) 

{ 

Draw.ZTest = CompareFunction.Always; 

Draw.Matrix = parentTransform.localToWorldMatrix;

Draw.BlendMode = ShapesBlendMode.Transparent; 

Draw.LineGeometry = LineGeometry.Flat2D;

Draw.Line(new Vector2(-1, 1), new Vector2(-1, -1), 0.05);

...
