Environment: - Qt 4.6.2 - Windows XP When trying to extract pictures from QwebView, we have incoherent result and sometimes crashes. Using provided application: - run setup.bat - qmake -r - nmake Then run (either release or debug). This will generate a batch of images in subfolder pictures, expressing the differential update (exact position and size is expressed in name file) Issues: - some pictures are incoherent : test693_50_261_750_104.png - clic button : View_fullscreen (the one circled in red in "overview.jpg") and hold it : it crashes. crash looks like a race condition on FrameView.cpp, line 1013-1014: unsigned size = m_repaintRects.size(); for (unsigned i = 0; i < size; i++) ScrollView::repaintContentRectangle(m_repaintRects[i], false); When the crash happens, size != m_repaintRects.size()
