Do "normal" applications look blurry on high DPI screens?
You can opt out of this on a per-app basis (right click app icon, Compatibility tab, select "Disable display scaling on high DPI settings") and have them just display everything really tiny if you prefer that. This is actually a decent option if the app has its own scaling but doesn't properly interact with Windows to enable it. I still run Sublime Text 2 and have it set to disable High DPI scaling and then just use a bigger font point size to make the text readable; also used to do the same with Chrome back before it had proper High DPI scaling on Windows (disabled DPI scaling, then just used the normal web page render scaling).
