Hi,
I have the same problem. The content in amarok's libvisual window slows down in cycles. Not nice. Played around with driver update and realtime kernel without any success. No idea, what else to try.
opensuse 11 32bit, default kernel 2.6.25.20
Nvidia Geforece 7050 PV /Nvidia Nforce 630a
AMD Sempron(tm) Processor LE-1250 at 2.2GHz
drivers:
x11-video-nvidiaG01-173.14.18-0.1...
