        <pre>I get display glitches with xf86-video-intel-2.20.13 on my Gentoo Linux system.
They vanish when downgrading to xf86-video-intel-2.20.12. I'm going to attach a
couple of screenshots after submitting this bug. They show an empty Mozilla
Firefox window, but it's not a Firefox specific thing. You should look closely
at the address bar borders and at the close button "X" cross. They look ugly
with 2.20.13, but they look good with 2.20.12, instead.

I don't know if it is related, but my system also have <a class="bz_bug_link 
          bz_status_RESOLVED  bz_closed"
   title="RESOLVED FIXED - [GM45 SNA] gtk3 tab rendering demonstrates error in opacity shader"
   href="show_bug.cgi?id=57054">bug 57054</a> with 2.20.13.

Some additional informations:
