Wish I had a fancy oscilloscope that could take screenshots, but this will have to do:
That's measured at the Xout / Yout from the PCB. See the blue vector that looks nice, and see the red vector that is noisy as hell? Predictably, the blue vector is rock-solid on screen and the red vector jumps / shakes around and looks terrible.
What is the analog circuitry doing differently when drawing those two lines? Before I start randomly replacing expensive chips -- what do you think it's doing different for those two lines? The output voltage should be roughly the same so what the heck is the difference??
