[Bug 478584] [NEW] [Karmic] Xorg eats 100% CPU in certain situations
Public bug reported:
Binary package hint: xorg
When I run Audacity and I record voice from analog line input on sound card Xorg eats 100% CPU, even if Audacity is minimized. I've experienced the same problem with some other applications, too and my friends got this problem in Karmic installer (Ubiquity) on Radeon 9000, 9100 and 9200 (R2xx). I use Radeon 9600 which is RV350, and I've been upgrading from 9.04 and couldn't test the installer.
All the tests where done with Kubuntu (I don't know anyone near me using Gnome).

(I've set Xorg to 15 nice priority but at 0 it's the same as here)
