network indicator animation makes compiz use 30% CPU

[Andreas E.]

When searching for a wireless network, the network indicator shows an animation. While the animation is active, the compiz process increases to over than 30% of CPU usage (from average 2%) and the computer becomes hot and the fans loudly turn on.
For an animation of ~25×25px size this is abnormal.
