Can confirm, updated to version 0.5.0 and got this bug, same for the latest git commit

This seems like an issue with the sysinfo crate. I tried logging the old_rx_bytes and rx_bytes the crate keeps track of to find the number of bytes received since the last refresh and they were equal. Can anyone confirm whether this is true so we can open an issue in the upstream repo?

In the meantime, we can keep track of the total bytes received (which is correct), and calculate the difference in eww. The total bytes could also be exported in the EWW_NET magic var this way.

Another workaround would be to get the total bytes before and after running the networks.refresh().
