QWebEngineView makes black window after hibernate or log off.

[CKurdu]

I created an object that inherits QWidget. It has QWebEngineView. When I hibernate my Windows 10 then I open again only this widget shows black window.

It should look like that.

Thanks adance.

@CKurdu Sounds like https://bugreports.qt.io/browse/QTBUG-51892
Are you using Qt < 5.8? The above bug was fixed in Qt 5.8

[CKurdu]

No, I'm not using Qt <5.8. It happens each of versions 5.8,5.9. I have Nvidia GForce 920M. I will test it later on another computer. Maybe, the problem is related to the bug.
