e.g redrawing the preferences menu takes about three seconds here. 00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 current rawhide x86_64. (ok,intel driver is one build behind because of https://bugzilla.redhat.com/show_bug.cgi?id=496614) on the same hardware F10 redraws in normal speed.
Unable to reproduce on i386. Exactly what kernel and driver builds are you running?
Ok, with xorg-x11-drv-intel-devel-2.6.0-14.fc11.x86_64.rpm menu redraw is normal speed. (uptodate rawhide with todays kernel-2.6.29.2-126.fc11.x86_64) I am suffering from hangs with the intel driver when playing a movie in mplayer (already bz'ed). The last non-hanging driver for me is xorg-x11-drv-intel-2.6.0-14.fc11.x86_64 and with that xmms menu update is slow. waiting for a fixed intel driver.....
Core text performance (which is almost certainly your xmms performance problem) has been fixed since 2.6.0-14 and accompanying kernel and libdrm updates.
ouch, copy and paste error... kernel-2.6.29.2-126 + xorg-x11-drv-intel-2.7.0-4 renders the xmms menu fast but crashes with mplayer/xine and friends. kernel-2.6.29.2-126 + xorg-x11-drv-intel-2.6.0-14 renders the xmms menu slow. (i am not sure if i should interpret "has been fixed since 2.6.0-14" as "2.6.0-14 should already be fine" though) Konrad
