the view of paraview

I use paraview 5.7.0, when I load the state file and data, if I change the view of the model ( hold on the left of the mouse to rotate it), it has a lot of balck dots. Could someone help to solve it?

here I attached some photos. Thanks a lot.

Do they go away when you stop moving the camera? If so, ParaView does some decimation when rendering during interactions to help keep things more responsive.

You can increase the LOD threshold to solve that issue.
