Hi and welcome to devnet forum

Also the questions asked in response are still the same. Without more information nobody can help you.

The version of my QT is Qt5.7.0, and my os is windows 2010 . I used Qt4 before and there was no error but when I updated the qt version from Qt4.8.6 to Qt5.7.0 I got the error. Once I resize the window, all in the window turn to be black and there is nothing left. Any other information I can offer for you?
