Comment 1 Owen Taylor 2004-02-04 15:21:30 UTC 
This doesn't look like a GTK+ or Pango bug, but rather a 
problem with the Xrender libraries. You'll need to debug it
yourself/ and/or report the problem to bugzilla.freedesktop.org
or to HP, depending on where you got the Xrender library.
Comment 2 Olivier Fourdan 2005-08-03 15:03:41 UTC 
For the record, the problem is with libXrender (including latest version 0.9).
The problem shows when the display has the XRender extension (ie it doesn't show
with the regular HP console, it shows when using a display on a recent linux
distribution). The following patch fixes the issue for me.
