Bug Description
I noticed that compiz CPU usage was a little on the high side after I noticed some sluggish desktop performance. I opened up htop and noticed that the CPU usage was only high when audio was playing. I use Audacious as my music player. The high CPU usage continues as long as audio is playing, regardless if the audacious window is visible or not.
I recorded a video with recordmydesktop and attached it, for easier viewing it is also available on youtube http://
Notice how Compiz starts out nice and low CPU usage, then as soon as I begin playing audio it spikes up and stays high, even as I minimize the window. Then I stop the audio and CPU usage returns to normal.
