Piano sustain pedal has issues in playback/MIDI with tempo changes.

Issue type

General playback bug

Description with steps to reproduce

I’m not sure if this issue has been posted before, but I’ve encountered a problem that mainly occurs when there’s a tempo change, usually after more than 30 bars.

In bar 33, the issue persists, and starting at 185 BPM, the sustain pedal playback shows unusual behavior. It might be related to tempo markings, but I’m not certain. The problem only happens during tempo changes. (The rit. markings are disabled and are just text, as are the fermata markings.)

This song was created entirely from scratch using MuseScore 4.4, but the issue also occurs in MuseScore 4.2 and possibly in the first version of MuseScore 4.0. This inconsistency can affect playback quality. Deleting and re-adding pedal markings does not resolve the issue.

I have attached the video and the link to the file for download.
