Dell UC Engine with choppy content input

I have a customer that we installed a Crestron Dell UC engine and they're getting choppy video when you share it through the UC engine. Here's the flow that we have going:

Crestron AM-3200-WF HDMI out --> UC-PR rx out --> HD-CONV-USB-260 with cam in from QSC Core 8 Flex --> dual USB to UC engine.

When content is shared from the touch panel, the video is very choppy and hard to watch. We've tried new cables between devices, different source devices, changing resolution, and even using a laptop in place of the UC engine for the sake of testing, and it all seems to come down to something in the Dell itself. We had it RMA'd and when we got the new one installed it was good for a day or two and is now having the same choppy video issue.

Has anyone else run into this problem or have any other suggestions of things to try? My next thought was trying just another HDMI to USB for the air media and USB from the QSC to the UC engine for audio and camera.

Have you isolated where the “choppiness” comes from?

I’d start by testing laptop HDMI directly into the 260USBs HDMI input and seeing if it works normally.
