I have a small pile of OLED button modules that I can get to display the test gradient and display in reverse but as soon as I try to give it an image the screens just fill with identical garbage.

Does however respond to reset and blank commands.
The panel is known good and has firmware version 2. I can confirm it's specific to these buttons as if I put known good ones in (same firmware versions) I can get images to display. Yes I have also reflashed both the panel and buttons.
