If you downgrade "cairo port" it will be ok. If you update ports tree

fix is available.

Yes, so far so good.  Downgraded to cairo-1.10.2_3,1 and have not seen the
garbling problem again.

Just picking the last message in the thread.

I found a Xorg bug report about the cairo 1.12 corruption. I will
investigate this more closely tomorrow since I about to fall asleep. It
seems there is a issue in EXA. People with cairo 1.12 should try to disable
that and see if that helps. I think that can be done by putting the line
below in your xorg.conf.

Option "NoAccel" "true"
Yes, it's what I have collected from in Google search as well.

--------------------
* Pixmap (and bo leak) during fallback glyph composition

* Remove broken acceleration for rendering glyphs directly upon the
   destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix
   another Pixmap leak upon fallback handling).
--------------------

Another for xorg-server 1.12.x:

https://projects.archlinux.org/svntogit/packages.git/tree/trunk/EXA_Fall_back_earlier_and_more_thoroughly_from_exaGlyphsV2.diff?h=packages/xorg-server

Can people try this and see if it fixes the problems? http://people.freebsd.org/~kwm/patch-cairo Just put it in x11-servers/xorg-server/files/ and rebuild xorg-server. Works for both 1.7 and 1.10.

I can't reproduce any of bug here with nvidia-driver as I have been
running for three or four days by now with GNOME 2, Firefox 12 and
etc.
