Hi, BUG: All basic operations like navigation (C-p, C-n,..), typing in the minibuffer, etc are extremely sluggish.. latency in the order of 10s of seconds! I am seeing this bug since the emacs built from master yesterday and even in the latest build as of writing this email. The bug is not seen when running emacs -Q&. But it is seen if try to get "emacs -Q" behaviour in emacsclient. So I moved my actual init.el to a temp file and add just the below code in the init.el (require 'server) (if (not (server-running-p)) (server-start)) - After that, start "emacsclient -a '' -c &". The *scratch* buffer should open in a frame. - Now when you do something simple like C-p, you won't see the cursor move at all. But as soon as you try to type something, it will get typed on the above line, that too with a huge latency between the moment you hit a character and that char showing up in the *scratch* buffer. I believe this to have been caused by this commit: http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=5c9304ea86b8cfc9d0b6d7769b90bd56e5dd1313 In GNU Emacs 25.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.23) of 2015-10-01 Repository revision: 9c86325b69d75e9b17ff468f5a2220597979635f Windowing system distributor 'The X.Org Foundation', version 11.0.60900000 System Description: Red Hat Enterprise Linux Workstation release 6.6 (Santiago) Configured using: 'configure --prefix=/home/kmodi/usr_local/apps/6/emacs/master 'CPPFLAGS=-fgnu89-inline -I/home/kmodi/usr_local/6/include -I/usr/include/freetype2 -I/usr/include' 'LDFLAGS=-L/home/kmodi/usr_local/6/lib -L/home/kmodi/usr_local/6/lib64'' Configured features: XPM JPEG TIFF GIF PNG RSVG IMAGEMAGICK SOUND GPM DBUS GCONF GSETTINGS NOTIFY ACL LIBSELINUX GNUTLS LIBXML2 FREETYPE LIBOTF XFT ZLIB TOOLKIT_SCROLL_BARS GTK2 X11 Important settings: value of $LANG: en_US.UTF-8 value of $XMODIFIERS: @im=none locale-coding-system: utf-8-unix Major mode: Fundamental Minor modes in effect: tooltip-mode: t global-eldoc-mode: t electric-indent-mode: t mouse-wheel-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t blink-cursor-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t buffer-read-only: t line-number-mode: t transient-mark-mode: t Recent messages: For information about GNU Emacs and the GNU system, type C-h C-a.
