On normal working with nothing opened, compiz fires up to 50% CPU usage on my machine. Which is abnormal I think.

Is this a bug or is this behavior ok?

I am running Ubuntu 12.04 on Intel i5 processor
ATI 5400 mobility 512 MB Graphic card

  • Can you provide the output of glxinfo | grep render?

  • nope, it is not at all okay Jun 2, 2012 at 9:19
  • Ok, so your graphics chipset is recognised and video driver is loaded, one possible reason could be if the software renderer is used, then compiz might cause high CPU usage. But clearly that is not the case here.

Had the same problem. Compiz constantly at around 40% (AMD CPU, ATI 58xx, 12.04). Then i followed this post https://askubuntu.com/a/127310/26508 and CPU utilization dropped below 10%. Hope it helps.
