Transparent parts and other GUI bugs v10.0.20

Hello

Since last update to 10.0.20, I have a lot of bugs in the GUI.

Transparent parts when create news one.
Transparent faders in the mixer.
And default color scheme loading every time that open Cubase, needed to re-select my custom color scheme in the Preferences.

Any ideas? Solutions or suggestion?

Here is one of these “problems” in spanish, sorry: Cubase Elements 10 - Taller de Sonido - Parte 1 - Producción Español - YouTube

Thanks to all!
