waveshaper and quantum bug

I found a bug that makes a sound indefinitely
I don't really know how to explain this, but the best I can do is tell you how to reproduce it.

Place down a synth, then connect a quantum then connect a waveshaper
Double click on the graph of the waveshaper to add a node and then drag it all the way to the top left to make a perfect square wave, then play any note on the synth and the sound should appear.

Here is a draft just in case

Funny thing :)
The sound itself is some kind of over-amplified LSB-noise and is kind of expected with this wave-shape.
But it should be possible to stop that sound somehow. And it shouldn't make a difference if the synth has stopped playing or if I unplug the cable. Turning down all volume controls before the waveshaper doesn't affect that sound either.
@kurpingspace2 pointed me to the fact that the noise depends mainly on the lower frequency of the quantum. You can use it as a radio searching for a signal :)

Haha ... wouldn't do that. As this is most likely undefined behavior, you might end up with satanic messages in your song once we change something.
