Bug Description

Binary package hint: pavucontrol

Everything else appears fine, it just takes 100% cpu while open. Closing it fixes the problem. This is always reproducible.

I can see a clear rise in CPU usage when I have pauvcontrol's "Input Devices" tab open. The rise is due to pavucontrol and especially Xorg taking more CPU, but not more than some 10 %. I think it's the drawing of the input level that causes that. However, selecting a less busy tab lowers the CPU usage again to around 1 - 2 % (which I still think is excessive).
