IndexError: tuple index out of range

[AlexWhitehouse]

As title, index error occurs randomly and UI is scrambled between graphs and the error.

Resizing the window or pressing any key returns the UI to normal and removes the error

I don't have this IndexError, but sometimes when I start nyx, it looks similar to your screenshot.

Ctrl+C shows the following call stack:

Traceback (most recent call last):
  File "/usr/bin/nyx", line 33, in <module>
    sys.exit(load_entry_point('nyx==2.1.0', 'console_scripts', 'nyx')())
  File "/usr/lib/python3/dist-packages/nyx/__init__.py", line 176, in main
    nyx.starter.main()
  File "/usr/lib/python3/dist-packages/stem/util/conf.py", line 289, in wrapped
    return func(*args, config = config, **kwargs)
  File "/usr/lib/python3/dist-packages/nyx/starter.py", line 133, in main
    _shutdown_daemons(controller)
  File "/usr/lib/python3/dist-packages/nyx/starter.py", line 254, in _shutdown_daemons
    controller.close()
  File "/usr/lib/python3/dist-packages/stem/control.py", line 1103, in close
    super(Controller, self).close()
  File "/usr/lib/python3/dist-packages/stem/control.py", line 753, in close
    t.join()
  File "/usr/lib/python3.10/threading.py", line 1096, in join
    self._wait_for_tstate_lock()
  File "/usr/lib/python3.10/threading.py", line 1116, in _wait_for_tstate_lock
    if lock.acquire(block, timeout):
KeyboardInterrupt

Also sometimes when I leave nyx, it hangs.

Seems to be a multithreading issue. Deadlock probably...

I have the same problem - and resizing seems to fix it temporarily. Additionally, I no longer have the connections page showing active connections, though I'm not sure if it's related.
