When the fullscreen player is expanded and the song is playing. The memory usage will increase sharply.

The issue has been identified. The problem lies in the dropShadow effect in the song cover file Cover.kt. After applying this effect, whenever a Composable rendered below the Shadow undergoes recomposition, it causes memory growth. The PlayerProgress component below ExpandedScreen happens to recompose frequently due to its animation.
