I let my code run for over an hour. .No hangs what so ever. I ran it as wifi AP not client and I have it hooked up to a bench supply with no actual Pixels connected.
I changed the code to update 300 pixels (that aren't really there) ... Did you change it or run it as I posted?
Here is my sketch I used for debugging, running on a ESP-07

Guys, I cannot get mine to disconnect while running as a client. Is it possible you guys are using an older wificlient than I am? I recently updated mine directly from the github sources, as the the package installer kept installing older sources.
