Hi! Sorry about this - I think the issue is with bit-ordering (in Graphics.createArrayBuffer we changed the default value to be msb-first in new Espruino builds)
I've just updated the display driver modules for the LCD/OLED screen to explicitly ask for little endian, so if you try uploading again now it should work (without the need for mirroring in setRotation)
