[Bug 969860] Re: [fglrx] compiz uses 100% CPU when screen turns off


I can always tell when my screen is blanked because my CPU fan is
roaring.  I on an HP elitebook with Radeon HD 6470M graphics and am
running the fglrx driver.

I found that it takes about a minute for the CPU to start spiking after
the screen blanks.  From running top, compiz goes from 0  (for about the
first 20 seconds) to 30 to 100.

I ran your script in a loop every 5 seconds, there are approx 26 runs in
that file  The last stack in there may show it starting to wake-up as I
bumped the mouse during the last trace.

If I can gather more info, please let me know.
