Depending on the selected font (and at different sizes) i regularly
see garbled renderings.  these usually take the form of several glyphs
in a font missing some part of their body, often entire horizontal
stripes missing.

This happens in different applications, so i think it belongs to the
underlying font rendering library.  If you think it should be
reassigned to something other than pango, i would welcome a suggestion
of where.

I've attached two screenshots (made with "xwd | convert -
bad-font-$whatever.png") that capture two different examples of broken text.

in bad-font-iceweasel.png you can see that the lower-case "t" is
missing part of its stem.

in bad-font-gnome-specimen.png you can see several glyphs are chopped
up.

Let me know if there is more debugging information i can provide.

fwiw, i've now updated my kernel and xorg to newer versions
(2.6.37-1-686 for the kernel, and the versions below for the xorg
packages), and moved ~/.fontconfig out of the way in case there were any
cached data causing problems.

I don't see the same problems with the same glyphs since this set of
transitions (i know, i didn't hold enough variables constant to make it
a good scientific experiment), but now new glyphs fail to render properly.

Any thoughts on what i can do to get to track down this bug?  I can read
around the mis-rendered glyphs myself, but it makes it awkward to do
things like show a presentation to a group of people.

I'm looking at another bug which seems to manifest itself as a
misrendering of text (604680 and 616392).  This bug seems to appear on
machines using the i945GM.  It's unclear whether what you're seeing is
related, but just to be thorough: is the machine on which you're seeing
the corrupted text using an Intel 945GM or other Intel GPU?

Hi Brian--

Thanks for looking into this!

It's not a 945GM, but it is an intel GPU:

Let me know if i can give you any other info.

It gets worse and worse.
Now many sites seem to have big <del> style cross-out lines through
words. Not just like ---, but two lines, ===.

And of #@$& course, when one tries to Acquire a Gimp Snapshot, they
disappear just in time.

That only leaves using a digital camera as an option.

Well maybe if someone really intends to fix this then maybe I will take
a picture.

thanks
Firefox is getting less and less readable these days.
Can you please stop it from doing this. Thanks.
