(SOLVED)Plugins in Channel Settings windows not highlighted blue (Windows 10)

Hi there,
I upgraded from Windows 7 to Windows 10 and now when I open the Channel Setting window of any track, the insert active plugins are not highlighthed light blue as it used to be before - like e.g. here the VSt amp rack: https://steinberg.help/cubase_pro_artist/v9/en/cubase_nuendo/topics/mixconsole/mixconsole_using_channel_settings_c.html?hl=channe%2Csetting%2Cwindow

Does it have anything to do with Windows color settings or Cubase itself? How to fix it?

Thanks

edit: it seems that Windows10 needed a new graphic driver, after update it went ok
