Getting the data onto the screen is fine, and IRL I can't see any flicker, but the OLED screen itself is apparently refreshing at something like 107 or 133 Hz.

Yep, it should show on the screen but unfortunately the camera refresh rate is out of sync with the screen's refresh rate so it's a bit hard to see. I need to read the datasheet again and drop the screen's refresh rate - I tried adjusting the camera's instead but it was never quite right.
