Any pointers on where to > look in our systems would be appreciated. between 2.2 and 2.14 there are at least 5 years worth of changes. what version of cairo are you using? can you profile things using massif (memory usage) and oprofile (cpu usage)? ciao, Emmanuele. -- Emmanuele Bassi, W: http://www.emmanuelebassi.net B: http://log.emmanuelebassi.net _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
