Warning: Screen changes have been received after the expected state was seen.
This is probably due to an indeterminism in the test. Try adding
`wait()` (or even a separate `screen:expect(...)`) at a point of possible
indeterminism, typically in between a `feed()` or `execute()` which is non-
synchronous, and a synchronous api call.
Note that sometimes a `wait` can trigger redraws and consequently generate more
indeterminism. If adding `wait` calls seems to increase the frequency of these
messages, try removing every `wait` call in the test.
If everything else fails, use Screen:redraw_debug to help investigate what is
causing the problem.
