suddenly I have this problem. In the main window in 3D Viewport all objects (excl. ref images) are not visible while viewport shading is solid or wireframe, even the outlines. In material or rendered is everything as it should be.
In my secondary window it's ok and I can see them. When I select an object in the second window I can transform it in the main window. I just don't see it there, only in the main window. And in the main window is this weird "shadow" wich is formed like a pyramid. The settings for the viewport (at least the screenshots below) are the same for both windows.
Does someone know where I can switch that off?
I use Blender 2.82
