Playback lag when there are many notes
OS: Windows 10, Musescore Version: Musescore 3.6 portable for Windows
It always happens with the harp glissando at the end of the attached file, but it only in certain sessions will it happen in other places. It can happen on any score with enough notes, and on most soundfont instruments but certain ones seem to be immune. It appears to happen after a certain amount of notes, but that amount varies from session to session and if they are spaced out enough, it's fine. It's a really annoying issue that seriously interferes with playback.
By the way, when it plays, there is memory and processing power to spare.
