Yes, I am pretty sure it would be reproducible with any evdi client on such systems.
About contributing - thank you for the offer.
In fact, I have just published a very simple client for evdi - completely unrelated to DisplayLink hardware - but with full source code, with an intention to show how evdi can be used. Hopefully this can make some reproductions and diagnostics easier (as I am certain you could reproduce most, if not all, issues with such client, too)
