True, a good working GPS can handle high speed, no doubt about that.
But when the GPS signal is weak, or the drone thinks that the GPS signal is weak it will not process this data correct. When the drone moves to another postion (more speed gives more distance...), than the new actual position is a different to the one that the drone thinks where it is, as the updating position is not done correctly.

The satellites transmit at a constant power.
If the drone has an unobstructed skyview (like this one did), there's never a weak GPS signal.
When the drone moves to another postion (more speed gives more distance...), than the new actual position is a different to the one that the drone thinks where it is, as the updating position is not done correctly.
If this happens in flight that the warning GPS postion mismatch is seen, thus a mismatch in actual postion and stored postion.
The app would display a speed error if that happened.
Happens sometimes flying near buildings ect wich more GPS signal reflection, and/or when the receiving sats are close to each other in the sky.
GPS pos mismatch warning 99% of the time for very short moment, but it is not a false warning made by DJI engineers to confuse us....
But since it has no effect on the drone flight, it is, in effect a false alarm.
It's something that means nothing and has no detrimental effect and doesn't indicate any real problem..
