Bug 87922 – [Qt][WK2] Contents not rendered in MiniBrowser for some pages

• Component: WebKit2
• Status: RESOLVED FIXED

[Dinu Jacob]

Contents are not rendered in MiniBrowser for some pages like google.com though the page has been loaded successfully

[Dinu Jacob]

For these pages the comparison between accurateVisibleRect and drawing area contentsRect in QQuickWebViewFlickablePrivate::_q_onInformVisibleContentChange is true.
drawingArea->contentsRect is actually returning the contentsSize and this is set by the time we reach this slot. Thus the drawing area visible contents rect is not set correctly. For pages with contents height greater than the viewport bounding rect height, it gets set when the content size grows beyond the viewport bounding rect height.

Added a new patch that attempts to compare the actual visible contents rect of drawing area and the new value to determine early return in  _q_onInformVisibleContentChange.

Should we close this bug? It seems all patches have landed and the issues are fixed.

[Michael Brüning]

This came up on the pending commit list sent around on Eric Seidel. The patch has landed and the issues have been fixed as far as I saw in a test, so I am closing this.
