Hello Fabian, 

Do you face this issue with any specific model or even with simple model created in SpaceClaim? 

It could be beneficial to reset the user settings from SpaceClaim Options > Advanced > Reset All User Settings.

The main thing we recommend in this type of situation is to make sure the drivers for the graphics card are up to date.  
Make sure to go directly to the card manufacturer's website to check for the latest version.

Regards,

Devendra
