Using Google Pinyin input method in QTextEdit , the cursor was not visible

[tiaoweiliao]

I'm using Qt 5.3.1. windows 7 64bit.

My code is very simple. in main().

Qt Code:
QTextEdit textEdit;
textEdit.show();

When I input Chinese in QTextEdit with Google Pinyin input method, the cursor was not visible,and I couldn't make it visible.

The cursor displayed correctly when I used any other input method.
