Hello Guanpeng Xu, I'd suggest you to file two seperate bugs at https://bugs.kde.org/ . This issue is probably worth a bug report, as I read from your reference that it occured at least on two different systems. And a bug report will not get lost. Please also add some informations about your system to these bug reports: - What are the font rendering settings in systemsettings? - Which versions/flavors of freetype/fontconfig are installed on your system? - What are the display settings in systemsettings? Cheers, Julian
