Qt WebEngine Crash on new MacBook Devices (15-inch, 2018 and newer)

When we run our application on new MacBook devices it crashes as soon as it starts rendering web pages (even simple web pages like www.google.com results).

The same application perfectly runs on older MacBook devices with same OS Version.

It does not seems to be a problem of OS version, more it is related to HW accelerator (expecially related the graphic one). Using a different HW but same OS version we have not problems.

We compile the project using QT creator running on a PC with XCode10 installed

We have no crash using QT 5.9.8 but the system using this release on that MacBook is really slow.

 

Please find the crash logs at the end of this email.
