Hi Gyan, 

I've met this before. However, several factors may have effects on the rendering, including the type of graphic card, the OS, and the version of matlab. It is too complex to examine their exact relationships. So, a possible solution is to try using another computer or a virtual machine. Another option is that you may try to switch the render from opengl to zbuffer in the global section of the option panel. It sometimes fixes some unexpected issues.

Best,
