About 3 to 4 hours after turning on my PC, compiz 'memory usage' rose from 300MB up to 1.5GB!
What is happening? What is wrong?

Here is the screen-shot from system monitor:

It seems like a bug, mine doesn't move beyond 150MBs no matter what. do you have any of the extra plugins enabled (those not installed by default , i mean, that can be found in synaptic. i think they are called "compiz-plugins-unsupported" or something like that) If not, you should probably send a bug report –  Chriskin May 8 '11 at 20:55

I think it was because of "window preview" plugin. it's on compiz-plugins-extra package. when I disable it, launch-bar and panel went black! and when I run unity --replace memory usage decrease to about 50MB –  Behzadsh May 8 '11 at 21:02

Warning: the previous command should be unity --replace & when executed from the console. –  egarcia Dec 14 '11 at 10:27

It is a memory leak, probably in multiple places. It should be fixed by Compiz developers. It has been filed as a bug. Please mark yourself as being affected

+1 I would guess that too –  Aleksandr Levchuk May 9 '11 at 4:54
    
I think so, I thought it was because of extra plugins but it happened again, and by restarting unity memory usage coma back to 25MB –  Behzadsh May 9 '11 at 9:28

I was running into this, and just running "unity --replace &" was enough to drop it from 1.5GB down to about 110MB. I'm guessing Unity is telling compiz to create buffers that Unity is failing to tell compiz to clean up. At least I have a reasonable workaround.
