From ade9babee1fda207ea560c469b1c8876c732e729 Mon Sep 17 00:00:00 2001 From: claude-code-best Date: Sat, 20 Jun 2026 22:51:28 +0800 Subject: [PATCH] =?UTF-8?q?revert:=20=E7=A7=BB=E9=99=A4=E4=B8=BB=E5=B1=8F?= =?UTF-8?q?=E5=B9=95=E5=91=A8=E6=9C=9F=E6=80=A7=20self-healing=20=E9=87=8D?= =?UTF-8?q?=E7=BB=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 回退 f69c7051 中引入的 ink.tsx self-healing 机制（lastMainScreenHealTime 字段 + 每 5 秒触发全量重绘 + needsEraseBeforePaint 主屏幕分支）。该机制在 workflow 面板持续刷新场景下表现为可见的"重复刷新"，且修复效果不稳定。 alt-screen 的 needsEraseBeforePaint 路径和 prevFrameContaminated 字段保留， 它们仍服务于 handleResize / layout shift / selection 高亮。 Co-Authored-By: glm-5.2 --- packages/@ant/ink/src/core/ink.tsx | 31 ------------------------------ 1 file changed, 31 deletions(-) diff --git a/packages/@ant/ink/src/core/ink.tsx b/packages/@ant/ink/src/core/ink.tsx index 37d3a91c7..60da7d94d 100644 --- a/packages/@ant/ink/src/core/ink.tsx +++ b/packages/@ant/ink/src/core/ink.tsx @@ -165,12 +165,6 @@ export default class Ink { private frontFrame: Frame; private backFrame: Frame; private lastPoolResetTime = performance.now(); - /** Timestamp of last periodic full-redraw in main screen mode.
