htop: https://imgur.com/a/jgzo3Gk flowgraph: https://imgur.com/a/2XN4Z35 I included a picture of the topology just incase I've missed anything glaring with it, although I did not change much at all to the example. I should note that this is the first time I have seen any activity on the correlation graph, as well as the HPD parser error, which I believe occurs when something is wrong with a packet. The CPU load looks fine so is this a bug I'm dealing with? I had prior issues with this example on 3.8 and 3.9, and even have done a complete fresh linux install since then.
