As spotted by Windows United, Microsoft has acknowledged a firmware issue causing display problems on their Surface Pro 4 devices, which reportedly appeared this past summer. Multiple threads on Microsoft's Support Forum point to issues with inking and touch, as a direct result of July's firmware update for the 2-in-1 range.

The firmware update created driver problems specifically pertaining to Surface ME, Surface embedded controller firmware, and Surface UEFI, each displaying a "(code 10)" driver error. You can see if you were impacted by going to your Device Manager (right click the Start button, and select Device Manager), and by looking for yellow warning triangles with the (code 10) error.

If you were impacted by the firmware problem, Microsoft is reportedly allowing users to get a replacement via the Surface Support website by talking to a member of staff and describing the above driver issues, although further details about exactly what caused the error are still elusive.
