Package: libpango1.0-0
Version: 1.28.3-1+squeeze1
Severity: normal
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.
