After upgrading to x11-drivers/xf86-video-intel-2.14.0 yesterday, the text in Emacs (emacs-vcs-24.0.9999) is garbled. For example, when scrolling a buffer, text of a scrolled away line is displayed at the current line overlaying its real text. There are some strange symbols here and there, and basically emacs becomes unusable. This happens only in X11 emacs frames. Emacs in a terminal doesn't have that defect. The display recovers to normal state after some seconds or when switching away from emacs to some other window. However, directly when switching back and modifying the text in the emacs buffer or scrolling, it's garbled again. I wanted to create a screenshot, but since the display recovers as soon as switching away from emacs, I couldn't do that... (Hm, maybe I could create a screenshot by using a timer. If you need one, please tell me so.) For now, I've downgraded to x11-drivers/xf86-video-intel-2.13.0 which solves the issue for me.

Same problem with emacs-23.2-r2.
I may have a hunch. Could you attach your full Xorg.0.log? Thanks
Created attachment 259656 [details] The full Xorg.0.log
I'm now running the 2.14.0 intel drivers and mesa-7.10 (formerly I used 7.9.1), which arrived in portage today. That seems to have fixed the issue for me. I cannot reproduce the bug again.
Ah... so you are using a compositor?
My experience is not the same as Tassilo Horn's, comment #4. I have xf86-video-intel-2.14.0, mesa-7.10, and cairo-1.10.2. I still get artifacts with both emacs-2.32-r2 and emacs-vcs-24.0.9999. Yes, compositing. I'm using compiz. If I use metacity without compositing emacs is fine.
@Derek, please open a bug upstream [1] and paste the URL here so we can track the issue. Thanks
(In reply to comment #6) > My experience is not the same as Tassilo Horn's, comment #4. Oh yes, I was a bit too fast. Although it seems to be much better with mesa-7.10, I still get artifacts in emacs here and there. And yes, I use KWin with desktop effects turned on, so it's also with compositing.
(In reply to comment #7) > @Derek, please open a bug upstream [1] and paste the URL here so we can track > the issue. It seems there's an upstream bug. I've added a link here and there: https://bugs.freedesktop.org/show_bug.cgi?id=32734
This bug seems to be resolved upstream, and applied in debian and others as well: https://bugs.freedesktop.org/show_bug.cgi?id=33650#c10 http://permalink.gmane.org/gmane.linux.debian.devel.x/95747
Created attachment 264157 [details, diff] The (one line) patch that fixes the corruption This is the patch involved. It fixes the issues on my system.
It should be fixed in xf86-video-intel-2.15.0, please reopen if you still see the problem in that version.
(In reply to comment #12) > It should be fixed in xf86-video-intel-2.15.0, please reopen if you still see > the problem in that version. No, thanks, it works fine now.
