QT5 Text rendering issue

问题

I have cross compiled QT5 on a MIPS based platform. Whenever I run application including sample apps, (Which contains text), first it draws the text and later paints the area of text with "rectangle" fill of Text Color.

So finally I see a black rectangle all the places where text is displayed. If i change the text color, the color of rectangle also changes. Has anybody faced this issue? Any suggestions?

Even when I run qtwebkit, I see that URL part, the text in any HTML page is painted with rectangle fills.

Thanks
