[Qt-interest] QWebView Blinks In GL Accelerated QGraphicsView

[Karol Krizka]

Hi all,

I am working on an animated UI in Qt, so I'm embedding QWidgets in a
QGraphicsView. However, when I turn on OpenGL acceleration in Qt 4.5.0
by setting the viewport to a QGLWidget() and embed a more complex
widget, like QWebView, the widget starts flickering when I move my
mouse over top of it. I have this problem on both Linux (Gentoo) and
Windows (XP). I didn't have this problem with Qt 4.4. Has anyone
experienced this before?

I'm using the following code:
#include <QApplication>
#include <QGLWidget>
#include <QGraphicsView>
#include <QGraphicsScene>
#include <QWebView>

int main(int argc,char* argv[])
{
    QApplication app(argc,argv);
	
	QGraphicsScene scene;
	QGraphicsView view(&scene);

    QGLWidget viewport(&view);
    view.setViewport(&viewport);

	QPushButton wdg;

    scene.addWidget(&wdg);

	view.show();
	return app.exec();
}
