Legacy applications font scaling is blurry in build 10586

This question I'm sure has been addressed many times, yes? I just made a purchase of a Dell Inspiron 13 5000 2-in-1. The system is a pearl accept for the font display in the legacy applications and OS widgets. The only solution seems to be to adjust the font scaling and set the DPI value to 125%. This makes everything smaller, yuck! My question, has anyone seen the same on any build 10586 system and then see the problem go away by installing the August update build 14393? Because that is the only software related change I haven't tried. Updating Intel display drivers had no effect.
