--- Comment #12 from Roderick Colenbrander thunderbird2k@gmail.com 2010-05-18 10:22:26 --- The fade to black bug is likely the same. Either it uses RealizePalette as well (it is quite common for fading effects) but even if it is not the real bug is read_from_framebuffer_texture which just doesn't flip the surface which it has to do. The issue is not gpu / driver specific at all.
