There is an issue on the QWebEnginePage::DesktopVideoCapture in x64, Debug and Release.
If I try to use it, it always crash the software.
Test was done with this page https://www.webrtc-experiment.com/RecordRTC/
Microphone + Camera is working on the version indicated.
But FullScreen is not working.
I tested with other website. the same.
A crash occur inside Qt dlls
In debug x64 on Windows 7 x64 (I already tester the version 5.12x and 5.13.x on Windows 10 and this is also crashing)
