QtWebEngine

@Ferdinand-Castelino In the screen shots you show libraries, not packages. How to add dev package depends on how you created the sysroot and what Linux distribution is running on your device. On Ubuntu this package is named "libnss3-dev". Dev packages contain header files and what else is needed to build software which uses a library, it is not enough to install the library itself.

@Chakra2811 Since this is a PyQt question, if you do not get an answer here you could try asking the PyQt folks over at https://riverbankcomputing.com/mailman/listinfo/pyqt

still think the components that are used in examples should be included by default or at least if nothing else warned that you wont be able to do some examples unless you have them (in the right places mind you, not tucked away in some weird documentation). It would also be nice if there is gonna be typing completion in qmake, cmake, etc., that it actually be contextual to the syntax of those items and not just spit out seemingly random tags most of which don't have anything to do with said files... even better, maybe include at least the headers that way you know for sure you are missing the library instead of ghostin' the whole kit'n'kaboodle.

@therealmatiss Qt 6.8 does not support Ubuntu 18.04 (see https://doc.qt.io/qt-6/linux.html). Use an older Qt version which supports this Ubuntu version (which does not get any support anymore by the way).

Thanks. Created one https://bugreports.qt.io/browse/QTWB-77

thx for your reply

First upgrade to a recent version. If the error still persists, create a minimal, compilable example. And if it then still exists it might be a bug in Qt not yet fixed.

@gfxx The OS is Windows 11 22H2

@Haowei-Hsu you saved my day ^^. Thank you. Qt Positioning really fix this issue on my Qt 6.8

GGnome provided the solution to this problem in this thread. Setting the following in my main.cpp before initialising the app cured all performance issues with my WebEngineView: QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);

Thank you @GGnome ! I was having a slightly different problem (ghosting, tearing, stuttering, flickering, etc.) and I use the QQuickWindow line you've posted above and it completely fixed it. I don't remember seeing anything about that particular setting in the documentation...I must have missed it.

Problem solved. server name was not set up in /etc/hosts after reinstalling Ubuntu.

@_qt-qt_ Please either run configure with -v parameter or do what it suggests: Configure with --log-level=STATUS Then you will get more details, else nobody can tell why it is not detected.
