Camera Interpolates Entering First Person When It Shouldn't
In every single SRB2 version, going into first person has always been an instant jumpcut. This is because certain things about the game are made visible or invisible while the game is in first person, so a transition period would make the difference obvious.
However, in 2.2.11, with the introduction of uncapped, this is no longer the case. The camera interpolates between the third and first person camera, and when going from the former to the later, the player completely disappears. And when going from the later to the former, the player's sprites are right in your face.
This seems entirely unintentional and probably should be addressed.
