From 295a2a6fa336906cfc233907cebeabf6b8ce9012 Mon Sep 17 00:00:00 2001 From: yuquanjun Date: Thu, 10 Sep 2026 10:46:11 +0800 Subject: [PATCH] Fix song-name trailing ghost by clearing the full text row before redraw. When switching from a longer title to a shorter one, the old gradient-only clear left uncovered glyph fragments outside the pill bounds.
