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: https://youtu.be/WWGdybx6apw?t=875

Thanks to all!
