MOZ_QT_GL=1 enabling QGLWidget backend for toplevel qt window

This error dumped in console, and no GL scene rendered:

layout/generic/nsGfxScrollFrame.cpp, line 3144
glGetProgramiv GL_ACTIVE_ATTRIBUTES failed: 0x00000501
JavaScript error: , line 0: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsICanvasRenderingContextWebGL.drawArrays]"  nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "JS frame :: http://learningwebgl.com/lessons/lesson01/index.html :: drawScene :: line 173"  data: no]
And this works fine when MOZ_QT_GL=1 no exported.
Presumably something is not properly ensuring the correct context is made active?
MOZ_QT_GL already hacked into current OGL layers system...  but is not valid anymore
