Hi,
First of all, the flickering was even worse in 5.12.5, but is still there, depending on the performance of the host device.
I have a class, which is a QQuickWindow and receives a QML including WebChannel and the WebEngineView. I'm rendering an image, which I get from an external camera and 3D content as overlay (so that you know, it is an AR application). I have the following issues:
- The rendering of the camera image already takes up a lot of the GPU resources.
- The WebView is extremely slow. I also observed it from the "Qt Simple Browser" example in Qt. The same things I do there, in a normal chrome browser it runs much faster
- Flickering happens, when I use Intel Integrated Graphics (on NVidia it is not there or only minimal) - on Windows. On Linux it doesn't really happen.
I tried a few things already, I cannot count them all. For example, I disabled AA_EnableHighDpiScaling or activated Qt::AA_UseOpenGLES and some other things.
So, there are actually 3 problems I cannot find a solution to:
1.) Image rendering takes up too many resources
2.) Webview is extremely slow
3.) The flickering problem
Can anyone help me out?
Thanks in advance.
