Interestingly, it is a TUV 4 error for me. Opened the two textures in Paint.net, saved them again, changed to TUV 0.
Did some further testing: It is (somewhat?) caused by something related to lightning. Turning exterior lights on/off causes that stutter every time, though that does not explain why those stutters appear when driving as well. Tried deactivating the part that changes the display over to driving mode, no change. Sometimes, when driving, the display lights up for a single frame when that stutter happens.
But as far as I can tell that stutter has nothing to do with that weird TUV error caused by the blank texture, since it happens on all display modes, not just when driving/turning the lights on/off.
