ok. i also added some profiling with oprofile. it shows the cpu-usage while resizing the frames inside sylpheed-claws. it seems that all cpu goes into memcpy operations. the same action with fglrx doesn't cause this.
the evas_benchmark file shows the performance differences between software- and xrender-rendering with radeon and fglrx. though the differences here are not so big that they could be the reason for the sluggish gtk and qt(it's also slow as hell) performance ** Attachment added: "xorg.0.log, profiles, etc." http://librarian.launchpad.net/6718770/radeon-txt.tar.gz -- [r300] ati driver unuasble slow (full cpu usage just for drawing gtk apps) https://launchpad.net/bugs/90604 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
