Hello Zhikai,
there are many things that can go wrong but as a guess from my part this is a problem with the display access. Maybe 
something is wrong with some of the many clock settings.

Is this happening only with a Qt application? Is running "gles2-gears" stable?

How long does it take for the display to become blue?

Are you sure the modlib matches your display and the clock configuration of the BSP?

Regards,
Albrecht
