UI font rendering screenshot
Description of problem:
UI font rendering is different to the others gtk2 program.
maybe hinting problem?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
rebuild freetype for byteinterpreter.
UI font :
* Korean : Malgun Gothic
* English : Segoe UI
It's quite likely that there's a small fix required for get the hinting mapping
the same as the pango/gtk one, autohint vs non auto-hint hinting type or
something like that, but is there a rpm available with "Malgun Gothic" in it ?
Or where does it come from.
Malgun gothic is MS Vista new default Korean font.

sangu: Can your hinting issue be reproduced (in devel) with any fonts available
for me to test with? Malgun Gothic is not available unless I have windows vista,
which I don't of course :-)
I'd love to be able to fix this, is there any other font that causes a similiar
problem that I could work with ?
I think I've identified the problem, I have a similiar looking problem with
Sorry about delay response.
This problem still happens in openoffice.org-core-2.0.3-3.2
This url is malgun gothic.
Using Meiryo for Japanese, Microsoft JhengHei for Chinese (Traditional),
Microsoft YaHei for Chinese (Simplified), this same problem will happen, maybe.
The fonts are cjk fonts which include cleartype(subpixel) and hinting.
I see this (other problem) now I think, GF_UNHINTED is hardcoded against not
having the TT BYTECODEINTERPTER available at compile time
// #95556# autohinting not yet optimized for non-western glyph styles
if( !(mnLoadFlags & (FT_LOAD_NO_HINTING | FT_LOAD_FORCE_AUTOHINT) )
&& ( (aChar >= 0x0600 && aChar < 0x1E00) // south-east asian + arabic
||(aChar >= 0x2900 && aChar < 0xD800) // CJKV
||(aChar >= 0xF800) ) ) // presentation + symbols
nGlyphFlags |= GF_UNHINTED;
got a new fix for that now...
