After the STIX fonts have been installed, the vertical bar/absolute sign doesn't stack properly. There are spaced between each stacked glyph. This was tested on Ubuntu 10.10 using the Gtk port.
The integral sign also doesn't stack properly.
you should post the faulty mathml code and associated screenshots if you want any chance of this getting fixed.
Created attachment 139801 [details] Visual proof I can reproduce the issue in EFL port (I'm assuming you would get similar results with GTK since we share fonts), see screenshot attached. It is easily reproduced with the following tests: - mathml/presentation/mo.xhtml - mathml/presentation/row.xhtml
This may be a STIX font problem? There was actually a similar bug report filed against STIX 1.0 (for integral sign only): http://sourceforge.net/tracker/?func=detail&aid=3136520&group_id=328428&atid=1378225

I'm going to attach a reftest to verify that the extenders form perfect straight lines.

Martin Robinson is working on a patch that fixes this problem on GTK and I guess EFL too, but it's not ready yet.
Created attachment 207069 [details] reftest
Created attachment 207070 [details] reftest (reference)
Attachment 207069 [details] and attachment 207070 [details] should render the same when this bug is fixed and should render differently on the GTK/EFL ports and probably others at the moment.
Note on the reftests: I really wanted to use narrower red bands (50px instead of 150px) but could not because of bug 119043.
