The current version available on fedora 17 already supports gtk3 but it's currently compiled to gtk2. It would be much better to have 24.1 with gtk3 going to updates.
emacs-24.1-1.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/emacs-24.1-1.fc17
please revert this! Such user interface regressions are an absolute no-go during a stable release. I wasted last 2 hours to find a working gtk3 theme but Emacs looks still ugly and important features like text selection are unusable due to contrast issues. Again: such a switch might be ok for rawhide, but not for a stable release were users do not want to see such breakage!
Enrico, thank you for the feedback. Do you use the standard GNOME 3 environment or something else? Do another GTK3 applications look fine? I run emacs-24.1-1.fc17 on xmonad and it works well.
Created attachment 597651 [details] appearance after 'yum upgrade' without further customization I am using xfce with Nodoka-Aqua theme. I will attach some screenshots; left side is gtk3 built emacs, right side the gtk2 variant: * first one is the appearance after 'yum upgrade'; gtk3 emacs is ugly and unpleasant. * second one is after selecting adwaida gnome 3 theme; emacs is yet more ugly (look at the scrollbar!) and contrast is a little bit low. Real problem is in other applications; delimiter bars in xfce4 starter menu have nearly the size of a half text line. * third shot shows window after searching a theme which does not show the problems from the points above. zukitwo looks nice (but is still far away from nodoka) but text selection is unusable due to low contrast.
Created attachment 597652 [details] after selecting default theme; yet more ugly and low contrast
Created attachment 597653 [details] another, better gtk3 theme but with contrast issues
Thanks. I prepared another update that doesn't switch to GTK 3. The switch from GTK 2 to GTK 3 thus happens only in Rawhide.
