[kde-freebsd] KMix in KDE 4.5.1 causing Xorg CPU usage to go up

[Jason E. Hale]

I just upgraded to KDE 4.5.1 and I noticed everything start to become very 
slugish.  I looked at top(1) and noticed the Xorg process using about 20% CPU.  
I didn't change any settings from KDE 4.4.5, but I tried disabling desktop 
effects and the CPU usage was still high.  I couldn't figure it out, so I 
tried closing everything I could.  I have always kept a kmix window open and 
didn't think anything of it, but as soon as I closed it the Xorg CPU usage 
went down to 0%.

I have kmix in the system tray and that doesn't affect anything.  It only 
happens when I click on the system tray icon and click the "Mixer" button to 
show the window.  I tried deleting the configuration files for kmix too.  I 
could just keep the window closed, but I like having it open since the system 
try applet only controls the first device and I use the second device 
freqently.

Is anyone else seeing this behavior?  I can reproduce it consistently.  I 
haven't noticed any other apps so far doing this.

FreeBSD 8.0 i386
NVidia driver (GeForce 8600M GT)

all ports up-to-date at time of writing
