QtWebEngine

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.

Any help here please!

For us it works with: // Disable pinch zoom in web browser qputenv("QTWEBENGINE_CHROMIUM_FLAGS", "--disable-pinch");

@jsulm no for sure ..... i try only the default installation with default project example before try to use open62541 on these new SO .... for check if all work. Pherhaps qtcreator 14 (desktop devlopment) is different from previous install on LMDE6 ... not understand how can change it .... seems compiler default is ninja .... not understand how to obligate system to use gcc .... there are not "set as default" options ...

@7erg Does it help to reduce the number of parallel build processes?

it's ok ,configure add " -qt-libjpeg -qt-libpng " parameters

it's resolve on debian 11,the problem repeat on debian 12
