S3 - Major
The playback is glitchy and the files are corrupted, and I can't write music and listen back to it. I will not be able to use musescore 4 until all of these issues are fixed.
Playback stutters when playing. It should not have anything to do with the difference between a 4 core and 8 core processors.
Still buggy on files that were not buggy before
