  1. Nice find.

    Simpler fiddle: http://jsfiddle.net/ak35o645/11/

    SpritePlugin calls renderer.resetGLState() which calls state.reset() which does this:

    currentColorClear.set( 0, 0, 0, 1 );

    That prevents state.buffers.color.setClear( ) from working properly in the special case in which the desired color is black and the desired alpha is 1.

  2. @lojjic It is best to restrict the gl call to one place, and call it only when necessary. Thanks for bringing this issue to the forefront, though.

    And thanks, @Neesnu.
