When IsAutoLayoutEnabled is set to true, LyricsStartX, LyricsStartY, LyricsWidth, and LyricsHeight are calculated automatically. If you want to customize these values yourself, disable IsAutoLayoutEnabled and set them manually.

By default, the ScrollViewer for lyrics is enabled. You can scroll using the mouse wheel and click on any item to jump to it. If you want to disable it, set IsScrollViewerEnabled to false.
