The model/simulation from this page: http://www.cip.ifi.lmu.de/~schubert/kovar/ correctly shows several points in Firefox, Safari and Chrome, but not on QtTestBrowser.
Tried both trunk (as of r86670) and qtwebkit-2.2 (8620c0c154d60999fd0d3573047d692b1dbcc4ce) with Qt-4.7 on Linux.
Check bug 16614 for a reduction and test-cases, as this problem was originally reported there (but fixed a long time ago, not sure why it still affects QtWebKit).
This is a bug in Qt's X11 paint engine, the example works fine with trunk and branch using the raster engine.

Testing with qt-4.7.x it's still broken. It works fine only with the qt-4.8 branch.
