I recently downloaded Blender 2.82a and I've been having some issues with the viewport. I have tried other versions of Blender, such as 2.79 and 3.0 and this issue doesn't happen on other versions. Whenever I go on material view, the model does this weird thing when I move the camera and it also doesn't show the material applied to it.
After I go on material view and go back to the solid view or wireframe view it looks like this. 
It happens on both Eevee and Cycles and my graphic drivers are up to date with the latest version. If anyone can help with this problem feel free to help!
