Interface chaos for Qt 5.9.1 Demo

tamlok

I wrote a C++ Qt GUI project in Qt 5.7. Currently I try to migrate it to 5.9.1. I found that the menu bar and tool bar were messed up. It looks like all the interface has an offset downward.

I opened a Qt built-in example "Qt Simple Browser" and found the same issue.

There is a large space between the title bar and the menu bar. Actually the menu bar is at the space. So if I click the space, in fact I am clicking the menu.

Any ideas? Thanks very much!

I found this after changing the search keyword: QML Display Bug

Then I upgrade the display card driver, and it works! So Qt 5.7 is OK with the older driver whilie 5.9.1 is not.
