Smiley turns alien
So I was testing the various subsytems of this custom SAMD21 board I made with a SAMD21E15B on a QFN32 adaptor board (complete with Arduino variant config) and I discovered that if the bit order in the bytes of the smiley image (which I have stored in an external memory and fetch via SPI to show in an Oled display) is the oposite of the one that the U8g2 library expects in drawXBM, the smiley turns into an alien.
Makes one think...
