Reproduction case is available here - https://github.com/StrangelyTyped/j3d-repro

When run it produces two renders from the exact same scene - a pair of ColorCubes rotated in opposite axes and intersecting with each other. The render-1.png shows the correct output regardless, both cubes intersecting. With ENABLE_BG=false, render-2 is exactly the same as you'd expect, but with ENABLE_BG=true then render2 shows one cube rendered on top of the other instead. Have attached all 4 images to this post just in case.
