  "textContent": "I found the problem. All you should need to do (in addition to the changes you already made) is set FilterPostProcessor’s internal framebuffer format:\n\n\n    fpp.setFrameBufferFormat(Format.RGBA8);\n\n\nFilterPostProcessor sneakily swaps out the viewport’s target framebuffer with its own before anything gets rendered, and uses a packed RGB format by default.\n\nEdit: interestingly enough, it seems that if the graphics driver doesn’t support packed floating-point textures, either RGB16F, RGBA16F, or RGB8 is used instead, regardless of what is passed to `setFrameBufferFormat`. So FilterPostProcessor could just randomly override whatever you pass in on some graphics cards.",
