The bug:

When you are using third person view, sound attenuation is not normal.

How to reproduce:

1. Turn on "Show subtitles" in the options.
2. Make a sound source that can be played repeatedly, such as a mob farm.
3. Move the player to just the right distance from the sound source, so that the sound is slightly attenuated but not gone.
4. Review what's currently in the subtitles, then press F5.
5. Review the content in the subtitles after pressing F5, then press F5 again.

The subtitles don't appear basically the same at certain angles.

The subtitles should be displayed in little the same way.
