    This is a known driver issue on Mali.
    Varying interpolation broken for flat axis aligned primitives larger than 2^14 * 2^14 with the conditions:
    - 1) 2 of the triangle edges must be aligned with the screen axis
    - 2) Triangle must be larger than 2^14 pixels along the x axis and the y axis
    - 3) Triangle must be smaller than 2^16 pixels along the x axis and the y axis
    - 4) The triangle vertices must all have W coordinate 1.0
