Strange graphics bug (?) in BMW cockpit

[schmocke]

Hi folks,
Since I moved my steam library folder to a new location I stumbled upon a weird graphics behaviour here. Right now, I think it affects vanilla BMW racecars only (did not check all cars with digital dashboard inside yet, but some): in cockpit view, there is no dashboard visible anymore, just a "dark display" on wheel. Maybe there's a switch, a keybinding I accidenteley hit? I reinstalled the game already, but the BMW displays stay plain dark. No mods installed here.

Thanks in advance for your ideas guys.

P.S.: please, excuse my English, it's not my mothers tongue.
