[Qtwebengine] OpenGL errors and crash

[Becsi Andras]

Hi,

What version of Qt are you using? Could you run with the —log-level=0 to see more information about what is happening?
This looks like a video driver bug, but if you think there is a bug in QtWebEngine, please create a bug report at https://bugreports.qt.io.

Thanks,
/Andras

Hi everybody,

i can't get QWebEngineView to work on my laptop with Arch Linux and
Intel 855GM Graphics - even with a minimal piece of code i get OpenGL
errors and the program crashes.

main.cpp:

#include <QWebEngineView>
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QWebEngineView w;
w.load(QUrl("http://google.de"));
    w.show();

    return a.exec();
}

test.pro:

QT       += core gui webenginewidgets

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = test
TEMPLATE = app

SOURCES += main.cpp

This compiles without errors or warnings. When i run it, i get the
following output:

QOpenGLFramebufferObject: Framebuffer incomplete attachment.
QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.
QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.
QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.

QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.
QOpenGLFramebufferObject: Framebuffer incomplete, missing attachment.
QOpenGLShader: could not create shader
QOpenGLShader: could not create shader
Speicherzugriffsfehler (Speicherabzug geschrieben)

Any hints how i can fix this?

Greetings,

Oliver
