The sensor's internal ADC supports a minimum line length of 3448 pixels, which may be too small to use with analog binning, where ADC operates on two lines together. Switch to a higher minimum line length of 3560 pixels to fix the blocky artefacts seen with analog binning [1]. To keep the same default framerate as before for all the modes, lower the default fll value to compensate for the increase in llp.
