Huge memory leak in Musescore 3.6.2

• Jul 4, 2024 - 21:15

To reproduce:-

Open up the attached mscz file. Play it, memory usage climbs up steadily until eventually hitting 12GB and the application freezes and needs to be force quit.

No leak here. Memory usage was 7.6Gb at start, went up to 7.7GB then back to 7.6Gb.
OS: Ubuntu 22.04.4 LTS, Arch.: x86_64, MuseScore version (64-bit): 3.6.2.548021370, revision: 3224f34.

No problems in 4. Slightly higher start at 7.9Gb, peaked at 8.0Gb, back down to 7.9Gb.
OS: Ubuntu 22.04.4 LTS, Arch.: x86_64, MuseScore Studio version (64-bit): 4.3.0-241231431, revision: 5f36e74.

(This is the total system memory being used and includes several other app's open at the same time. Memory use with MuseScore closed was 7.2Gb).
