Apple Music Lyrics Interface Lag Issues
Note that this issue has been fixed in version 4.3.52.
In the “Apple Music Lyrics” interface, switching to the second song results in noticeably more lag while scrolling the lyrics compared to the first song.
It may be a problem with WPF itself, which has existed for six months since the development of this interface began. Attempts to fix it have been unsuccessful so far. Currently, there is no solution.
