How to get rid of black noisy artifacts while using smooth groups brush?

[archz2]

I’m using Zbrush 2022.0.5

While using smooth group brush, I get black noisy particles while doing the operation. However, when I finish doing the smoothing, those noisy particles disappear. I’m using latest studio driver of Nvidia. I have GTX 1050Ti on my laptop on which use Z-Brush. This issue appears in all files of mine, whether new or old. I use my laptop like a regular person. No touch pad, no fancy mouse. Just a regular wireless mouse with three buttons.

My windows is upto date. What should I do to resolve this issue?
I made a screen recording to show what happens.

Hello @archz2 ,

Alright! Yeah. It only happens in polyframe mode. Is there any way to enable group colours in normal mode? That would help a lot to be more aware of sculpting near polygroup edges and totally rule out the black noisy artifacts.
