    Hello,
    I'm passing from rpi3 to RPI5 for my project but i'm having some troubles. Knowing that Raspberry Pi OS now uses Wayland (instead of X11) with Wayfire (instead of Mutter) by default on Raspberry Pi 5.
    OS version is : Debian 12 (bookworm)
    I have done the tests in two ways: 1- installed Qt creator 5 on my RPI5 2- did a cross compilation to send a package tar.gz ( my executables and theirs dependencies) In both tests, i had a black screen ( blank window) when displaying a test.qml.

    import ....

Window {
    id: window
    width: 500
    height: 300
    visible: true
    WebEngineView {
        id: view
        url: "https://google.com"
        anchors.fill: parent
    }
}

    Setting the QT_DEBUG_PLUIGNS=1 showed me this error: [78882:1:1116/060515.357037:FATAL:page_allocator_internals_posix.h(225)] Check failed: . : Invalid argument (22)

    So I decided to start with a smaller project since my project is complexe. The qt example of webengine "Quick Minimal Browser" that showed me the same error. What's the cause for this ? WebEngine doesn't work with wayland ? Did anyone face that problem ? Is it a bug that have been fixed in Qt6 ?

    @The-Qt-Mayssa hi and welcome to devnet,

    Do you have the same issue if you just show a dummy QtQuick application without webengine being involved ?

    @The-Qt-Mayssa I advise you to put WebEngineView in a page component
    import ....

    Window {
    id: window
    width: 500
    height: 300
    visible: true
    Page{
    anchors.fill:parent
    WebEngineView {
    id: view
    url: "https://google.com"
    anchors.fill: parent
    }
    }
    }
    Then try with EGLFS plugin

    i get this :

    Just to be sure, does this happen with the RPi provided Qt 5 ? Or did you compile your own version ?

    Misread the debugging output.

    Can you start Chrome on your RPi 5 ?

    Yes I can start chrome and for information i have installed the qt5 using the apt-install command. For sure it's long.
    In Qt.conf :

    [Paths]
Prefix=/usr
ArchData=lib/aarch64-linux-gnu/qt5
Binaries=lib/qt5/bin
Data=share/qt5
Documentation=share/qt5/doc
Examples=lib/aarch64-linux-gnu/qt5/examples
Headers=include/aarch64-linux-gnu/qt5
HostBinaries=lib/qt5/bin
HostData=lib/aarch64-linux-gnu/qt5
HostLibraries=lib/aarch64-linux-gnu
Imports=lib/aarch64-linux-gnu/qt5/imports
Libraries=lib/aarch64-linux-gnu
LibraryExecutables=lib/aarch64-linux-gnu/qt5/libexec
Plugins=lib/aarch64-linux-gnu/qt5/plugins
Qml2Imports=lib/aarch64-linux-gnu/qt5/qml
Settings=/etc/xdg
Translations=share/qt5/translations

    How could i know what's the default configration of webpageengine with an installation with apt and not a compiling my own versoin of qt?

    @The-Qt-Mayssa good question. I would check the parameters used by the package authors in case they do something specific for that architecture.
