I’ll apologize in advance for the sarcasm here.. I need to take another cheap shot at the Gnome developers here. GTK3 isn’t a reliable API. Maybe it should be called libgnome instead. GTK3.4 came with Gnome3.4, and wasn’t compatible with previous GTK3 themes. This means all GTK3 applications looked really ugly not only with all the GTK2 themes which don’t support GTK3 (almost all of them), but also the few which did. With this in mind we had three options:
- Give you a desktop with poor integration and applications which look different based on the API they use (which is completely unacceptable)
- Ditch all GTK3 applications from Mint and replace them with earlier GTK2 versions, or GTK2 or QT applications (this includes Gnome apps, but also Gdebi, Transmission and a few others)
- Rant like mad, remove all themes, and waste countless hours in giving Mint-X and Mint-Z proper GTK “3.4″ support even though it’s likely to break again in 3.6…
We went for option 3 “this time”. I hope this little example was enough to convince 3rd party developers not to use GTK3. I couldn’t find any release notes or documentation explaining the regression or how to solve the issue.. I genuinely get the feeling that GTK 3.4 is developed for Gnome 3.4, that it doesn’t really matter if it breaks things and that we’re not supposed to use it outside of Gnome.
