From 7ce34c9a947b17a8b5e81e7c2335a63552182d10 Mon Sep 17 00:00:00 2001 From: zeertzjq Date: Thu, 8 Feb 2024 11:34:55 +0100 Subject: patch 9.1.0082: Redrawing can be improved when deleting lines with 'cursorline' Problem: Redrawing can be improved when deleting lines with 'cursorline'. Solution: Use smarter invalidation and adjustment. Remove unnecessary UPD_VALID as it is already set at the top of the loop. Make the test for #4862 fail without the fix.
