Emacs-24.3-r2 doesn't like xorg-server-1.14.3: font rendering is quite weird, with some text/letters randomly showing up in any windows/buffer. Other artefacts occurs, f.i. superimposing another application window makes the text appear behind, but then moving that window away leaves an empty rectangle. I can't tell exactly what's the culprit between emacs and xorg-server, though downgrading xorg-server to v1.13.4 restore Good Behaviour. "emerge --info follows" (please note: that's for xorg-server-1.13.4, but v1.14.3 was compiled the same way). Reproducible: Always Steps to Reproduce: 1. Upgrade xorg-server to 1.14.3 2. Launch emacs Actual Results: Text is rendered with weird artefacts (invisible text, randomly scattered letters, etc.) Expected Results: Text should be correctly rendered Portage 2.2.1

I cannot reproduce the problem on an amd64 system with emacs-24.3-r2, xorg-server-1.14.3, and same USE flags (except for xnest which shouldn't make a difference). What X video driver are you using? xf86-video-nouveau? CCing X11 team, because the problem depends on the xorg-server version.
(In reply to Ulrich Müller from comment #1) > What X video driver are you using? xf86-video-nouveau? Yep, nouveau.
I have the same problem since upgrading xorg-server to 1.14.3. And it seems to be somewhat independent of nouveau. Using the nv driver doesn't change anything.

This could be an EXA issue. See what happens if you use xf86-video-modesetting instead of nv or nouveau.
And do you use any kind of compositing window manager? If so, does disabling compositing make a difference?
(In reply to Chí-Thanh Christopher Nguyễn from comment #7) > This could be an EXA issue. See what happens if you use > xf86-video-modesetting instead of nv or nouveau. Useing modesetting the rendering looks normal again.
(In reply to Chí-Thanh Christopher Nguyễn from comment #8) > And do you use any kind of compositing window manager? If so, does disabling > compositing make a difference? I don't use any compositing and the effect doesn't depend on the window manager in any form, I tried fluxbox, windowmaker, awesome and xfce4. Emacs looked the same on all of them.
my laptop uses Intel HD 4000 graphics, and I observed the same problem. Downgrading x11-drivers/xf86-video-intel from 2.99.906 to 2.99.905-r1 fixed it for me.
Please test something more recent.
I confirm that the issue doesn't occur any more with this set-up: app-editors/emacs-24.5 x11-base/xorg-server-1.17.4 x11-drivers/xf86-video-nouveau-1.0.11
Thanks for testing!
