Weird problem with Shading in Zbrush viewport.

Hello everyone,
I am having a bit of an issue with my Zbrush viewport. As you will notice in the pics I attached there is someone going on with the shadows.
Firstly, there is an annoying shadow on the sides of the jaw, that disappears after BPR or turning off “Shadows” in Render Properties and secondly, after BPR there are these white lines across my model, like lighter part of clay, that only get fixed by increasing the Angle in Shadow Properties.
Does anyone have the same issue ? Or my Zbrush or GPU are playing tricks with me ;o
I checked with other models, some tend to have it, some don’t.
I’d be glad for help ;o
