hello, when one uses alpha (alpha makes the bug visible) on a cube or cuboid (thats the geos i tested), and switches with the draw messages to wireframe and back the rendering of the objects becomes wrong. it actually is already enough to only send a draw fill message to mess it up. attached you find a patch to demonstrate it.
i would be very happy if somebody could fix this as i m using it in a work under development.
best + thx
