QtWebEngine

You either have to build QWebEngine (or WebEngineWidgets) from source if you want it for Qt 6.7.2. QWebEngine is available through the Qt Maintenance Tool only in certain versions. For example 6.6.2. I just upgraded from 6.6.2 to 6.9.0 but faced the same problem. Luckily, 6.9.1 (downloaded via Maintenance Tool) Includes Qt WebEngine Module for msvc2022_64, so I upgraded directly to 6.9.1.

Hi @Axel-Spoerl, Just checking in to see if you had a chance to look at the code I posted earlier. I'd really appreciate any insights or suggestions when you get a moment. Thanks again for your time and guidance. Regards, Soumyanil

Hello, @raphm01 Doyou resolve your problem? I have similar issue with terrible flickering of Webpage when using PyQT6 on windows OS

@wojciech_kazubski If you suspect the issue is related to the driver, post your problem in Nvidia forum and you may be able to be helped. Or you can download or build a new driver and try it out. On Linux, you can try to run your debug build with valgrind for some clues.

This issue is reported here: https://bugreports.qt.io/browse/QTBUG-136953. And there's a fix to qtwebengine-chromium: https://codereview.qt-project.org/c/qt/qtwebengine-chromium/+/646656

This command worked for me sudo pacman -S libxml2-legacy

I found the issue. When I migrated to the new QT Visual Studio tools upon being prompted by VS (I'm upgrading from Qt 5.15.0), this section was added to a higher level .props file where it was not previously. <PropertyGroup Label="QtSettings"> <QtInstall>Qt_Qt-6.9.0</QtInstall> <QtModules>core;gui;network;widgets;webenginecore</QtModules> </PropertyGroup> Deleting the "network" and "webenginecore" items got the webenginecore error to disappear.

Looks like this is going to be fixed in Qt 6.9.1, related patch - https://codereview.qt-project.org/c/qt/qtwebengine-chromium/+/634034

I've reported this issue as a bug at: https://bugreports.qt.io/browse/QTBUG-136652

Do we have a solution for this?

@DJBob-Gaming Is this spam? Does not sound like any answer to the question.

@Victorusik said in About version of QtWebEngine: And what does "debug information files" mean Those are debug files for Qt. You need them if you want to debug into Qt code (to see what happens inside Qt code).

@JKSH Thanks a lot for your answer!!! This question bugged me for days.

Does anyone know if the 32bit compilation of QtWebengine requires the 64bit versions of python2 and Node.js?

Additional thing: before start I set environment variable QTWEBENGINE_DISABLE_SANDBOX=1.

Hi and welcome to devnet, They might be using proprietary codecs, in which case you need to build Qt WebEngine with them enabled. See here.

did you able to fix the issue?
