From: Lars Magne Ingebrigtsen <larsi <at> gnus.org> To: bug-gnu-emacs <at> gnu.org Subject: 24.0.50; Possible bidi-related slowness Date: Sat, 10 Sep 2011 20:28:49 +0200I just experienced a massively slow Gnus article buffer. The following seems to reproduce the problem: (progn (pop-to-buffer "lala") (dotimes (i 197000) (insert "* 194624 FETCH (UID 194633 FLAGS (%Seen))\r\n* 194625 FETCH (UID 194634 FLAGS (%Seen))\r\n"))) If I hit `up' after that, Emacs takes about five seconds for each cursor movement. I haven't actually confirmed that this is bidi-related, though, but it's a recentish regression.
