GTK+ "GNOME theme engine designer Andrea Cimitan has implemented support for transparent widgets in the Murrine GTK theme engine, bringing Vista-like translucent glass effects to the GNOME desktop. Cimitan used RGBA colormaps to implement the feature and says that, with only 10 or 20 extra lines of code, translucency can easily be added to other theme engines that support RGBA. Cimitan says that the addition of translucency effects proves that critics of GTK are wrong. "[I]n the last week I've seen a lot of people claiming about 'lacks' of Gtk+ capabilities," wrote Cimitan in a blog entry. "Some of them still think that Gtk+ doesn't have RGBA support... Or it will require nasty hacks. This is absolutely false."

GTK is slow

The problem of GTK is that it's over-engineered. Conceptually, everything is ok. Every behaviors of the toolkit is well thought. However, the end result is much less exciting. A simple resizing operation causes a zillion fonction calls. Most GTK theme engines are unacceptably slow (the fact that they are almost all based on Cairo now is one of the causes for this). In a corporate environnement, I think people can live with that. For the rest of the world, I think it's not something you want. I have 2 computers here, one running XP and one running Gusty, and I see a huge difference between both setup even when doing the same exact task. For example, SWT/Windows is so much faster than SWT/GTK. Using Eclipse on Windows is so much more enjoyable than using it on Linux. Honestly, having Gnome, Evolution, Firefox, Eclipse and OOo running at the same time isn't something pretty even on a high-end computer. I know we can't blame GTK for everything but it doesn't help.
