Problems with QWebEngineView

euchkatzl

We just released our Software with qt 5.6.1 (updated from qt 5.3.2).
Therefore i changed all referenced from the old QWebView to QWebEngineView.

The Release was about 4 weeks ago and we have so many Problems on Windows Machines (on OSX everything works fine).
We have a 64 and a 32 Bit Application.

We just load a very simple Website (http://liberty.pdf-to-book.ch/updates/newspage/newspage_de.html) and the application crashes immediately when doing this. All Crashes seem to belong to opengl stuff.

This does not happen on every Windows Machine and it depends on the architecture.
Most of the Windows Systems had an Intel HD R Graphics Card.
The following List will lead to such crashes (on Windows 10) :

Intel(R) HD Graphics 4400
Intel(R) HD Graphics 5500
AMD Radeon HD 7400M Series
Intel(R) HD Graphics 3000
    --> works with 32 Bit
NVidia GeForce GTX 745
    --> works with 32 Bit

My first attempt was to deactivate OpenGl Support with QGuiApplication::setAttribute(Qt::AA_UseSoftwareOpenGL).
This solved a few Problems on Windows 7.
Then we encountered that this leads to crashes on modern systems (Win 10 etc.).

So i replaced the openglsw.dll shipped with qt with a newer version. (http://download.qt.io/development_releases/prebuilt/llvmpipe/windows/).
This solved more Problems but there are still a few.

My last Problems was with an Geforce GTX 745. Our 64 Bit Application did not run at all.

Not with openglsw (shipped with qt)
Not with openglsw (mesa 11)
Not with openglsw (mesa 12)
Not with normal opengl settings
Not with opengl es

The 32 Bit Application runs on that system with the mesa 11 openglsw.dll.

Here are as much Informations about this System i could get
