All of these issues have been fixed upstream now: - https://github.com/torproject/nyx/pull/45 - https://github.com/torproject/nyx/pull/46 - https://github.com/torproject/nyx/pull/47 - https://github.com/torproject/nyx/pull/48
So this bug can be closed when the next Nyx release appears and is uploaded to Debian.
