Full reset, format, clean install, etc.., are not solutions, there is a bug and Microsoft must solve it.
The fact the issue is related to a Windows update is only a supposition, but I am sure that the first day that I tried the surfaced I used the "Handwriting Personalization"...
My surface that I bought recently, in reality is quite old, is one first version of "Surface Pro 4", so the preinstalled Windows 10 build has at least one year.
@aureyano Maybe your default Windows installation is most recent than mine,
and the bug occurs even with a full reset.
Another hypothesis, is that the bug occurs after sync the settings with a Microsoft Account.
However I do not have the time to investigate, it's Microsoft that must solve the issue.
