From 0592fd5e17dc3609c148e0ccc25a4f035d5f7153 Mon Sep 17 00:00:00 2001 From: nwounkn Date: Sun, 24 Sep 2023 23:15:33 +0500 Subject: fix(ui): "resize -1" with cmdheight=0 #24758 Problem: Crash from: set cmdheight=0 redrawdebug=invalid resize -1 Solution: Do not invalidate first `p_ch` `msg_grid` rows in `update_screen` when scrolling the screen down after displaying a message, because they may be used later for drawing cmdline.
