After updating Rawhide today Emacs redisplay is dead slow. The problem is when scrolling: even when only scrolling by a single line, the whole window is redisplayed, and it is done so very slowly - taking about two seconds.
This is only a problem with the default "Gnome window" emacs - it is not a problem with emacs -nw (i.e. Emacs in a terminal window), or other text editors I've tried (kate, gedit).

Furthermore, it easily gets into a mode where keystrokes are misinterpreted.
Both problems are new as of today's update.
Anyone else seeing this? The problem is still there.
I created https://bugzilla.redhat.com/show_bug.cgi?id=487757 but it doesn't look like anyone has commented on or looked at it.
I worked around the problem by downloading and building Emacs 23.0.91, which seems to be working pretty well.

For your information, here is the feature request for Emacs 23: https://bugzilla.redhat.com/487615
Happy hacking, Debarshi

On the latter, you commented that "Apparently Emacs 23.0.91 solves [487757]". I didn't mean to apply that - that fact that 23.0.91 work for me while 22.3.1 doesn't could be because 23.0.91 was built with a different compiler, or configuration environment, or there might be some side effect of the package build process.
But if it could be confirmed then that would be an argument for upgrading Emacs even at this late date.
One experiement is I could try to download 22.3.1 from source and try to build it in the same way I built 23.0.91.
But first I'd like to hear if anyone else is seeing this problem - if not, that would be puzzling.

I have been using 23.0.91 with fine results. I can send you my .spec file if you like.
