qt application interface in a mess

[widon1104]

This problem happens in both ubuntu mate 16.04 and ubuntu mate 17.10
if I set "application font" to a bitmap font( vector font display effect is terrible), like "AR PL UMing CN Light"，qt application I use liteide or qtconfig-qt4 interface become in a mess.
First I think it's a qt's bug，but I find if I use gnome-shell and set the same font, everything is ok.(This problem only happen in mate desktop)
you can download liteide or just install qtconfig-qt4 to replicate the problem.
If you set "application font" to "AR PL UMing CN Light"，the qtconfig-qt4's interface will in a mess
