* Emacs+Ansi-Term Display Glitches @ 2011-12-26 15:30 Geoff Ferrari 2011-12-27 2:51 ` Vladimir Murzin 0 siblings, 1 reply; 4+ messages in thread From: Geoff Ferrari @ 2011-12-26 15:30 UTC (permalink / raw) To: help-gnu-emacs; +Cc: bug-gnu-emacs Hi, I'm experiencing some display glitches when using ansi-term to access a shell under the X11 version of emacs. There seem to be two separate glitches, and they're a little hard to describe so I've included a link to a video of the problem. FIRST GLITCH When I reach a full screen of text under ansi-term (i.e. once I've typed in a few commands and the history of these commands fills the screen, so that the input line is now at the bottom of the screen), the whole screen seems to either flash or jump every time I type a new character. SECOND GLITCH After I've either filled the screen using my own commands, or after I've used a programme such as top or mutt which takes over the whole screen, then the two lines at the top of the screen seem to persist. Running the "clear" command does not clear them, but they are cleared if I run the "reset" command. You can see a download a video (7.6MB) of these glitches from: http://cloud.geoffreyferrari.com/apps/files_sharing/get.php?token=db8e2a6726e03d1816548e17447a1df626215ac4 Both of these problems occur on both the latest 64-bit versions of ubuntu and debian wheezy. With the terminal version of emacs I get the second problem (lines being left at the top of the screen) but not the first (no display jumpiness). My version of emacs as reported in Ubuntu 11.10 is "GNU Emacs 23.3.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.5) of 2011-08-14 on allspice, modified by Debian" I wonder if there's anything I can do to remove these annoying glitches, of whether they are a bug that should be reported.

I checked and the configuration value on my machine for /apps/metacity/general/compositing_manager was already set to false. Changing to true didn't help either. Incidentally, my usual window manager is stumpwm and I get the display glitches there, too, so it might not be a problem with metacity in particular. One thing that helps the first glitch (the jumpiness when one has a full screen of output) is switching from char-mode to line-mode. There's still some jumpiness, but it seems reduced.
