I suppose you mean the changes related to Bug#71289. They should be here with the last one as commit 6fbb699bee2f54d65fbe6074735d42bbc0868c2c Author: Eli Zaretskii <e...@gnu.org> Date: Wed Jun 5 19:32:17 2024 +0300 ; Fix last change. Anyway, I pulled master again today, built with gtk3 and without-x and both exhibit the same behavior with MagicWrap (tty) == true curY (tty) == 4 FrameRows (tty) == 5 in cmcheckmagic after shrinking the TTY window with the mouse to less than two lines, slowly re-expanding it, at the time the split windows would have to be redisplayed because the frame apparently became large enough again. martin
