when flying the little bird on the editor i noticed that when i fly ( both when i press q, and z when in flight or landing too) that the main rotor seems almost stopped ( showing not much movement, like turning slowly) usally from looking at the same level of it, up to 70-80 degrees of from height ( sorry for english)

I know however that at times , like on cameras, screens, etc with a refresh rate such thing may happen because of the refresh rate and the high rotation speed of the rotor, but for now appears too often.
with the attached picture i try to show it. imagine that rotor, clearly visible as in the still ( taken during flight ), that just turns slowly .
Is it a Feature? {F16722}
