D-100 shows left bank after takeoff

When pulling onto the runway I stop for 30 secs or so and make certain the D-100 horizon is showing level flight.  As I release brakes and accelerate, the D-100 begins showing a 5+ degree left bank.  This isn't acceptable for an IFR departure and it concerns me. 

After about 3-4 minutes of flight, it improves greatly and operates normally.

Two questions: does IAS react normally at low airspeeds? And is there any residual turn rate (the magenta bar) when you're standing still? Regardless, we agree that it should not behave that way, and will likely want to see your D100 here at the factory.
