Turn Down, Rochade, 3D Venetian, Static, Fine Dissolve, Vortex, Ripple,
Glitter, Honeycomb, Newsflash.

Normal effects works perfectly, 3D-effects either don't work at all or when
played with F5, shows a flashing screen.
Tearing is also seen. Hardware acceleration is checked.

While the problem might be gone by the time we get to 6.3.0.0., for now I can
*confirm* that Olivier's observations. 3D-transitions do not work for me,
regardless if hardware acceleration and OpenGL are activated or deactivated.
