When directing the WebView to "http://webchat.freenode.net/", the site not only gets not displayed correct (corrupted), but also crashes when the user right clicks and selects "Reload". I tried this in Qt 4.7.0 and 4.7.1 - I think this is caused by the javascript on that site. Here is the stacktrace MSVS gives me: > QtNetworkd4.dll!QHttpNetworkRequest::operation() Line 240 + 0xb bytes C++ QtNetworkd4.dll!QHttpNetworkReplyPrivate::expectContent() Line 801 + 0xb bytes C++ QtNetworkd4.dll!QHttpNetworkConnectionChannel::_q_receiveReply() Line 395 + 0x8 bytes C++ QtNetworkd4.dll!QHttpNetworkConnectionChannel::_q_readyRead() Line 876 C++ QtNetworkd4.dll!QHttpNetworkConnectionChannel::qt_metacall(QMetaObject::Call _c=InvokeMetaMethod, int _id=2, void * * _a=0x003dd2c4) Line 92 + 0x8 bytes C++ QtCored4.dll!QMetaObject::metacall(QObject * object=0x037186cc, QMetaObject::Call cl=InvokeMetaMethod, int idx=6, void * * argv=0x003dd2c4) Line 238 C++ QtCored4.dll!QMetaObject::activate(QObject * sender=0x0371a230, const QMetaObject * m=0x67342060, int local_signal_index=0, void * * argv=0x00000000) Line 3272 + 0x27 bytes C++ QtCored4.dll!QIODevice::readyRead() Line 91 + 0x12 bytes C++ QtNetworkd4.dll!QAbstractSocketPrivate::canReadNotification() Line 640 C++ QtNetworkd4.dll!QAbstractSocketPrivate::readNotification() Line 77 + 0x15 bytes C++ QtNetworkd4.dll!QAbstractSocketEngine::readNotification() Line 155 C++ QtNetworkd4.dll!QReadNotifier::event(QEvent * e=0x003dd87c) Line 1104 C++ QtGuid4.dll!QApplicationPrivate::notify_helper(QObject * receiver=0x05a974b0, QEvent * e=0x003dd87c) Line 4445 + 0x11 bytes C++ QtGuid4.dll!QApplication::notify(QObject * receiver=0x05a974b0, QEvent * e=0x003dd87c) Line 3845 + 0x10 bytes C++ QtCored4.dll!QCoreApplication::notifyInternal(QObject * receiver=0x05a974b0, QEvent * event=0x003dd87c) Line 732 + 0x15 bytes C++ QtCored4.dll!QCoreApplication::sendEvent(QObject * receiver=0x05a974b0, QEvent * event=0x003dd87c) Line 215 + 0x39 bytes C++ QtCored4.dll!qt_internal_proc(HWND__ * hwnd=0x00080fa4, unsigned int message=1024, unsigned int wp=1832, long lp=1) Line 491 + 0xf bytes C++

I just tested the site with the FancyBrowser Example that is included with Qt - I get the same error there.

Please follow http://trac.webkit.org/wiki/QtWebKitBugs when reporing bugs here (missing Qt keyword). I have no problem with the site with WebKit trunk on Mac. Do you still have the problem or the site has changed and that cannot be reproduced anymore?

I can reproduce the issue with Linux and QtTestBrowser. I do have rendering issue but no crash when reloading the page. Steps to reproduce : - Open QtTestBrowser (and let the default size, do not maximized). - Go to http://webchat.freenode.net/ (do not log in). - Maximized the QtTestBrowser. Lot of rendering issue are showing. I suspect the page to not be properly repainted. With QGraphicsView mode there is no artifacts but a white background. Reloading make the rendering to work properly.

Well It seems it's for all websites not only this one.

Most probably related to https://bugs.webkit.org/show_bug.cgi?id=54865

I have no way to test this, but perhaps QWebPage::setViewportSize() now needs a call to setBoundsSize().

Comment 8 2011-02-23 08:37:54 PST
Or just change to call resize().

With trunk (r79441) it works perfectly. I can log in, chat and no crash. Qt 4.7.0 and Qt 4.7.1 includes quite an old version of QtWebKit (2.0 more precisely). We're working on an update.
