What OS are you on?

CMD E to go into CPU preview mode. You might have a problem using GPU preview.

Chris,

This GPU issue is fixed by Intel in their latest driver update (15.46.02.4729 - released on 11 JUL 2017 ) available at - https://downloadcenter.intel.com/download/26941/Graphics-Intel-Graphics-Driver-for-Windows -15-46-?product=88358

This update cannot show up driver search, as it might take some time for Microsoft to get it integrated in their Surface Pro driver updates. Microsoft prevents installing driver directly from Intel if you try the installer directly, however latest driver from Intel can be installed with steps listed in section "Update video adapter device drivers" > "Intel (Surface Pro devices)" in below link
