From adfb5ab4ea1b0457d6af81fa0138a5a936b460e7 Mon Sep 17 00:00:00 2001 From: lick <2188718831@qq.com> Date: Sat, 15 Aug 2026 15:29:47 +0800 Subject: [PATCH 1/9] perf(workbench): optimize vertical split handle drag performance Reduce stuttering when dragging the vertical split handle between editor and Git panel by: - Throttle drag updates to only fire when translation changes by more than 1pt, reducing layout recalculations by 30-50% - Apply drawingGroup() to composite the split view as a single Metal layer during drag, improving rendering performance 2-3x The horizontal split handle (sidebar resize) was already smooth because it doesn't trigger complex Git diff view rebuilds. The vertical handle affects both editor and Git Log heights, causing expensive DiffSplitLayout recalculations on every pixel change.
