Super Rub'a'Dub [NPEA00016]

On tub 5, the background is heavily flickering. Amd gpu+mesa.

Same issue, on every bonus stage apparently. It's kind of horrible, like legitimately needs a seizure warning horrible. Running on GeForce1080, problem persists on both Vulkan and OpenGL, strict rendering etc.
