           Summary: [GM45 SNA] No screen updates in some programs on
                    Ubuntu 13.10
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: freedesktop-bugs at PaulSD.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: Driver/intel
           Product: xorg

Just updated from Ubuntu 13.04 to 13.10, and I'm having issues running any
terminal emulator.  xterm, xvt, and gnome-terminal generally won't display
anything except my shell prompt unless I resize the window, but occasionally
will display a few characters scattered across the window if large quantities
of text are printed by a program.  Firefox, chrome, and gvim all seem to work
ok.  My gvim window occasionally becomes completely corrupted (displaying a
mostly random pattern), but I'm assuming that is a separate issue.

I'm using xserver-xorg-video-intel 2:2.99.904-0ubuntu2 with kernel
3.11.0-12-generic in Ubuntu 13.10.  In 13.04, I was using xf86-video-intel git
commit 504b18b079e0a12a9d18b46418411805ef1d8377 (because the
xserver-xorg-video-intel package that came with 13.04 had other corruption
problems).  Reverting my Ubuntu 13.10 system to using commit
504b18b079e0a12a9d18b46418411805ef1d8377 seems to fix most of the problems (I
still get an occasional line or two of text in the terminal that doesn't update
properly, or a line that gets repeated numerous times when it shuold only be
displayed once ... I did not observe such behavior when I used this commit
under Ubuntu 13.04, so there are obviously other components of the system
involved here as well).

I'll update this bug report with more information as I experiment further.
