Does anyone have thedemo example running for the Portenta Vision Shield?

I had to send an integer to start for the demo to even compile.

cam.start(3000);

My issues are very similar to the issues with the ov7670 Camera andJava Processing program except those issues were solved by switching from Windows to Linux. For the Portenta both Windows and Linux seem to have the zigzag issue for me using the Portenta Vision Shield.

It feels like the buffer is not getting properly reset, or it is just the Processing program that can't read the serial information fast enough. Does anyone know of a different Processing program thanhttps://processing.org/download/
