Open water swimming distance lag

A question for the Instinct Solar users who do open water swimming:

I own the regular Instinct.  When open water swimming, even if I've got a good gps fix and I have let it "soak" for a little, my watch continues to count meters when I stop swimming to take a break. At start it adds many meters per second and then slowly it settles but never stops counting. I know this is due to the watch doing calculations and route correction because the gps is extremely inacurrate underwater and the fact that the watch doesn't have the fastest CPU. But it just goes on for long and so if I press pause it will stop counting, If I don't press pause, I won't have accurate distance, pace, moving time etc..

As the Solar has different hardware my question is: Does this happen with the Solar Instinct too?
