Re: something odd with 3D view
It looks very much like a rendering issue rather than a wall/level configuration problem — especially since it also happens in a brand new file with default settings.
You could try the following:

Update your graphics card drivers.

If you’re using the installed version, try the other build (32-bit vs 64-bit).

Test with hardware acceleration disabled (if available in your version).

Try running it on another machine to confirm whether it’s system-related.
