Preview on GPU problem

Look at the series of images.  The only difference is when changing from preview on CPU to preview on GPU.  GPU is showing incorrectly.  This is a simple piece of art with no explanation for why this is changing.  In the GPU image, notice that the paths are straight yet the fill color appears to be following a different path, which is not there.  I included the outline view as well.

    Hi Larry,

    Thank you for sharing this. I would request you to please share your feedback here: GPU-Rendering doesn't work – Adobe Illustrator Feedback . This is the best way of communicating with the Engineering and Product Management teams regarding issues and suggestions so they can be implemented in future releases.

    Regards,

    Srishti

    GPU Performance has been an ongoing problem for many. It seems to need the perfect combination of graphic card, processor and divine intervention to work correctly. Unless you're computer savvy enough to attempt to switch or update your graphic card you will continue to have this problem when viewing with GPU Performance on. You can turn it off altogether in your Illustrator preferences. It is a very buggy option.
