Description
We are developing a windows desktop application that most of the business logic is accomplished with web pages which are embeded in QtWebEngine.
At first, the application works well, but after it runs for a while(it can be a few hours or a couple of days) , the webengine part rendered blank(totally blank or white or black). The UI thread gone dead, but background thread is running. The whole application needs to be restarted to recover.
The following output is found in Qt framwwork logs:

Everytime this problem happens, we can found"Display driver igfx stopped responding and has successfully recovered." message from the windows event viewer.
We had tried some methods to avoid this problem, for example, listening to QWebEngineView::renderProcessTerminated signal, and reload web page. That solves some of white screen cases, some other cases there is no QWebEngineView::renderProcessTerminated signal.
We suspect this is a bug either in Qt or the the graphics driver, but not sure.
