The airspeed indicator changes scale by 50% to larger increments at 300km/h, but the needle doesn't take this into effect until 400km/h, causing a 50 km/h difference in IAS. Hope I'm making sense here!

As far as I know IAS (Indicated Air Speed) and TAS (True Air Speed) really only ever overlap values at certain altitude due to air pressure. TAS is calculated based on IAS and air pressure...or something like that, maybe there's other variables.

The cockpit speedometer and speed displayed in the bottom left of the screen (if enabled) are IAS and if you go to no-cockpit view the speed in the HUD is in TAS. If this is the "bug" you're referring to...it's probably not such a bug as it is a feature from reality.
