Faces become distorted, strange and look glitchy when looking through camera view

Question

Whenever I attempt to create a test render (F12) or when I switch to camera view (Numb 0) my models faces look distorted. When I'm not looking through camera view, everything is smooth and normal, regardless of how close I am to the objects. When I switch to these modes the faces become distorted, strange and look glitchy. I've tried a couple things and have no clue what is causing this or what I can do to fix it.

One possible explanation I came up with is that the models have too much information inside of them, and the render isn't sure what to display. To solve this, I figured I could delete all of the vertices, faces, etc. inside of the model, but I found no way to do this. I'm at a loss.

Below is a screenshot from the work window in object mode followed by a screenshot of the camera viewpoint.

Answer 1

It looks like Z-fighting, probably the clip distances is set to a very large number.

The clip range should encompass your scene, not the whole universe. A large clip range will result in lower depth precision, creating Z-fighting, where the render engine cannot determine which surface is in front or which one is behind. In other words blender cannot tell apart faces that are parallel but in close proximity with each other.

Answer 2

Select your camera, go to the Properties Panel on the right and click the green camera Object Data properties icon. Under the Lens dropdown, adjust Clip Start and End. This may remove the glitchy appearance.
