    It seems that your contrast might be set a bit high.

    The random pixels can result from any mix of information that could be stored in the RAM for the display controller.
    Have you tried to clear the screen after initializing it?

    I was able to clear the screen after all and there are no random pixels.

    Although now my issue is that when I write black pixels to the lcd, the entire column goes white (as you saw on the image). Is this also due to contrast? I have it set to the value recommended in the datasheet init, so 0x10 (16/64)

    This is most likely due to the high contrast. I would recommend using a lower setting for the electronic volume.
    This will determine the pixel clarity.
