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
