VIP Scaler and Clipper usage

Hi, I've tested the following three design flows in SOPC builder and they work: 1. CVI(1920x1080@60Hz) -> Clipper(1680x1050) -> FrameBuffer ->CVO(1680x1050) 2. CVI(1920x1080@60Hz) -> Scaler...

As per discussion above, I am using:

CVI(1920x1080@60Hz) -> Clipper(320x180) -> FrameBuffer -> Scaler(1920x1080) -> Mixer(1920x1080) -> CVO(1920x1080)

This is working. But when I downscale like below, it doesn't work. I get a blank screen.

CVI(1920x1080@60Hz) -> Clipper(not utilized) -> FrameBuffer -> Scaler(960x540) -> Mixer(1920x1080) -> CVO(1920x1080)

What can I do to ensure downscaling works as well?
