uses 100+ MB of memory

[Mio]

compiz consistently uses between 100-2000 MB
for example currently:
  PID %MEM VIRT SWAP RES CODE DATA SHR nFLT nDRT S PR NI %CPU COMMAND
16686 8.7 677m 502m 175m 492 240m 41m 2 0 R 20 0 6 compiz
 7623 8.1 280m 117m 162m 1872 135m 18m 41 0 S 20 0 8 Xorg

i am using nvidia driver, ubuntu oneiric 64Bit fully updated
on a dualhead display(laptop + extra screen)
(also note: xorg uses lots of memory too.. may be related?)

an additional note: compiz --replace does not decrease the memory usage

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on the current 11.10 release. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at http://cdimage.ubuntu.com/daily-live/current/). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. Please keep in mind that the development version (12.04) is not suitable for daily use - please only use it for testing purposes.

Thank you for your help and patience.

using precise right now. It got better but still using at least 70MB.. right now at 118MB.. doing compiz --replace brought it to 84MB
will apport-collect as soon as it is at >100MB again
