Audio breaks when trying to play too quickly, but only in the app.

Steps to reproduce:
Create a score with quarter=40 and two staves (common time is recommended for this)
Make a scale in 128th notes in octaves
Do this on both staves (both hands on piano for example)
Try to play it.
However, it works when uploading the score.

Or, with the score I first noticed it on, Limitless, around m. 500 (the wild X shaped beams)
But uploaded at https://musescore.com/wilh3lm/limitless-wip it works fine.
The weirdest part of the audio degradation is that it doesn't happen on the site, just the app.
WARNING: Limitless is 400 KB
