The bad problem I see now is that Emacs and Chromium-browser, which rely on gtk3 don't work properly anymore. In Emacs, the symptom is that the ribbon of buttons under the pull down menu will no longer show. In Chromium, the buttons and other widget things on the top are an ugly yellow distortion.
Un-intuitive as it may be, you may just need to start using either the Adwaita or Clearlooks-phenix theme.
One chap I know of that's using the CERN linux told me that solved a problem similar to yours by using the clearlooks-phenix theme.
I use clearlooks-phenix here to solve a different set of problems (menus on Gnome-terminal and Geany), and I don't really like the way Adwaita looks.
Here's the solution if you want to try it:
yum install clearlooks-phenix-gtk2-theme clearlooks-phenix-gtk3-theme
Go to the look and feel preferences setting on your desktop and select Clearlooks-phenix from the list.
And afterward you can
yum remove mate-themes
if you want because it's not needed any more (assuming that you're using mate, that is).
