set_brackground() transfer time longer than image transfer #1

Closed NemoAndrea closed 4 months ago

NemoAndrea commented 4 months ago

Sending an image with set_background() of all 0 values takes ~5x longer than sending a 2560x1440 png image that is all zeros.

Suspect: implicit conversion in python code that is taking a while.
