Why some panels and interfaces appear so blurry?

Suddenly some options panels and others panels became blurry. Anyone has passed through this problem before?!

Is the interface scaling on windows set to 100%? By default it is normally 125% and lately I’ve found windows to display some text as blurry on my 1920x1080 laptop screen.

Thanks for your input but the problem is not that.
This issue occurs only in certain windows, like in Rhino Options/Advanced, Plug-ins, and Render panel. Some popups appear like this too.
