Description of problem:
I upgraded to Fedora 12 and to my surprise, some Chinese text that used to be displayed correctly now appears to be rendered ugly and broken.
Examples can be found in the attached screenshots. All shots are taken on the F12 system. Unfortunately I didn't take shots on the previous, working system (because it worked as expected) so there's no comparison.
On my current F12 install the font packages are almost the same as the previous F11 system. There are no additional fonts installed.
The installed CJK fonts are:
I'm not sure whether this bug should be reported against this package or any of the font packages. I really don't know. I just guessed this could possibly be a fontconfig problem, since I didn't change the fonts.
The Appearance setting is also inherited from the previous install. The default font used is "DejaVu Sans 9". In F11 it used to do the right thing with this setting (displaying Western text in DejaVu Sans and render CJK text beautifully). I didn't change anything.
Also, subpixel antialiasing seems to have stopped working for CJK text too.
Version-Release number of selected component (if applicable):
I guess the cause of this issue is complex, but I have to choose a package to report the bug against ;) If you feel it's necessary, please also inform the font maintainers of this issue.

F12 YUMEX screenshot
The rendered text in the red circle is the most offending. Also the larger characters doesn't appear quite right even with subpixel on.

F12 GIMP screenshot
The small characters displayed in this GIMP sidepanel appears utterly illegible.
Can you reproduce in gucharmap? And identify which font has the problem?
try to search "antialias" in the conf.d folder. UMing should set 10px (or 11px) as the smallest font size for antialias=false.

Thanks for the comment. Lowering the threshold value seems to have fixed the problem for me.
Any reason for the particular choice of 10px or 11px? The GIMP seems to require a smaller value to display the small characters properly.
This should be fixed in F13 already btw since I dropped the bitmap .conf there.
Perhaps you could test the current rawhide/f13 package is ok for you?
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
I have test yumex, gimp and imchooser on my F13 machine, it is ok for me. The problem have fixed in F13.
