Hi,
Think i can't of great help here, but at least twice when i had slow
graphical performance solved it by re-emerging some packages and
xorg-x11 once (i assume you have run 'revdep-rebuild' ;)
As it seems your main DM is KDE it's likely that there may be issues
with GTK-apps, as their libs/deps also get loaded when mozilla/etc is run.
Here's some info:

IMHO you could first try emerging: glib&gtk+ and probably in second
place: xorg-x11.
There are also many image-manupulation libraries: jpeg,png,mng
