I programmed a preset for WinAmp's AVS which I enjoy a lot. But I wondered if I could convert it to the MilkDrop 2 system. Well, that turned out to be not as easy. And I may have noticed a serious bug.
The MilkDrop 2 plugins in WACUP and foobar2000 differ obviously. While this reports version 2.41.4 and supports up to 4 custom shapes and waveforms which it saves explicitly, that one identifies as version 0.8.14 and supports up to 32 custom shapes and waveforms which it saves minimalistically.
The elephant in the room here is that the phase display I programmed displays a long diagonal line when the visualizer window frame is clicked or moved, and the right channel spectrum is not visible, so I have to assume that the right audio channel contains garbage values beyond 481 samples of the waveform window (looks fine up to 481, starts messing from 482 samples upwards).
