Qt4 will fall back to software based overlay if it needs to, in which case the performance difference between the KDE3/Qt3 software overlay and the Qt4 software overlay should be minimal to nonexistent. Also, there will still be the Qt3 version available... > > http://www.thinkwiki.org/wiki/Neomagic_MagicMedia256AV > >> I am currently looking at the possibility of absorbing most of Qt3 into >> the Trinity project, and only using the core portions of Qt4 for the >> abstracted access to low-level system interfaces.

Not sure OTOH, but I would expect that any non-vesa-framebuffer drivers (e.g. ATI, Intel, nVidia, etc.) would permit at least partial GPU acceleration of alpha blending functions. > > As for Amarok, I don't use it.

Try gtk-qt-engine-kde3 and kgtk-qt3-kde3; they will skin GTK apps with Qt widget and allow the use of Trinity file open/save dialogs, respectively. > >> The last KDE3 version of KOffice is part of the Trinity distribution, >> but >> no active development is occurring at this time. > > Not an issue so long as it's maintained IMO. > >> You may want to ask Robert Xu; he is in charge of the >> OpenSUSE/RedHat/Fedora packaging.
