I just opened Illustrator and started a new document, but all of my type has these horrible white marks inside. What are they and how do I fix the issue?

Turn off GPU acceleration completely by clicking on the rocket in the control panel.

This 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-?pr...

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
