Are there known problems with nvcompositor or Opencv in r32.3.1?

I have a new Nano B01 and flashed it with nv-jetson-nano-sd-card-image-r32.3.1. It seems that the pure gstreamer USB video transfer is a bit faster, however programs using nvcompositor or opencv make problems. They are slower compared to the old kit and jetson-nano-sd-r32.2.1. Before I’m going to investigate it, my question:
Are there known problems with nvcompositor or opencv in r32.3.1?
Thank you in advance,
Best regards,

We collect quick fix for known issues in
No issue about nvcompositor is reported in r32.3.1. However, there is one in r32.2.1:
[GSTREAMER]High CPU loading in nvcompositor

Please share how you do the comparison. We would like to reproduce same observation and do further check. Thanks.

DaneLLL, thank you very much.
