**Title: ParaView shows strange black/white distorted viewport after zooming**

Hello,

I am using **ParaView on Windows**. Recently, the 3D render view suddenly became abnormal. After I zoom or scroll the mouse wheel, the viewport shows a strange distorted black/white image, like large triangular surfaces covering the screen. The model is no longer displayed correctly.

I tried reinstalling ParaView with different versions, but the problem still remains. So I suspect it may be related to the rendering settings, OpenGL, graphics driver, or some corrupted ParaView user configuration.

Here is what I observed:

- ParaView version: **5.13.3, 6.11**

- Operating system: **Windows**

- The problem happens in the render view

- It often appears after zooming with the mouse wheel or just like that when I open it

- Reinstalling ParaView did not solve the issue

- The screen becomes mostly black with large white/grey distorted triangular shapes

I have attached a screenshot of the issue.

Could anyone suggest what might be causing this? Should I try resetting the ParaView configuration, using Mesa/software rendering, or changing OpenGL/graphics driver settings?

Thank you very much.
