Some checks failed
Build for Windows / build-windows (push) Has been cancelled
- Defer eager-load scrollbar checks to next event loop iteration via QTimer::singleShot(0), fixing initial load not filling the viewport - Playlist search: eagerly fill viewport, then show "Load more playlists…" button instead of infinite scroll to avoid loading thousands of results - Increase search page size from 8 to 25 - Featured/discover playlists keep auto-scroll behavior unchanged Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
