Shading viewport glitches

Hi, my image of the mech is totally distorting and is having strange glitches in the shading viewport. Does anybody know what can be the cause of this problem? thanks!!

About how many Blender units tall is the object? About how many Blender units is the camera from the object? What is your viewport near and far clip set to (sidebar/view/clip)?

If you aren’t using an AMD graphics card, let us know!
