Absolutely historical, as no U Boat could stay same level for ever fully stopped!
Just couldn’t play without this negative buoyancy.

There was no automatic negative buoyancy when motors were stopped underwater. It all depends on how the boat was trimmed. As I said, standard practice was to trim about 1° down bubble at the lowest speed. In this case, if you lose that speed, you would tend to rise very slowly. The bigger issue with stopping submerged, which the game doesn’t simulate, is the loss of longitudinal stability in anything but calm seas. At any rate, keeping depth while stopped for a WW2 sub was a laborious and loud affair.
The exception to all this was the so-called practice of “hanging the boat by the periscope”. In calm seas, a well-balanced boat could poke a scope out of the water and shut its motors off and effectively hang there.
