Package: xserver-xfree86 Version: 4.3.0-2 This problem appears to be the same as reported here: http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2003-July/009690.html
>Description: XFree86 4.3.0 failed to render underline text if the text rendered using True Type font (freetype/xtt backend). >How-To-Repeat: Open mozilla / firebird , set the font to any ttf, surf anywhere. Notice that the links dont have underline, although we explicitly set 'Underline links' in mozilla/firebird preferences. I made the change recommended in the report above to Debian's 4.3.0, built it, copied the freetype module over the installed 4.3.0-2's copy, and it fixes the problem. (This is not as good a test as it could be, I know. The build failed later on for reasons I have yet to determine, so I wasn't able to install a full X with this change present throughout.)
