We've been fixing up a bunch of these issues recently. Are you still seeing this, or has it been fixed?
If it's still happening we can add it to the list of stuff to double-check.
Want to bump this and confirm its still currently happening. Noticing it on my Intrepid, where the bridge is supposed to be, part of the deflector, and several spots on the bottom of the engineering hull between the pylons. Also on the pylons themselves, and on the tips of the nacelles. Running in Dx11beta, with 2 6950s using the 12.1 drivers.
