Is anyone experiencing the same issues on Scout? I've tried AIR 19 through 22, and every kind of Context3D profile!
The simple act of applying a filter or drawing a rendertexture will trigger the error in Scout.
var renderTexture:RenderTexture = new RenderTexture(1024, 1024);
renderTexture.draw(new Quad(200, 200));
this is the exact Scout output, and I highlighted where the error occurs at drawTriangles. The error occurs when I add the Image to the stage (doesn't matter if I draw anything in the RenderTexture).
