Bug Description
Binary package hint: compiz
When compiz resize plugin is set to "normal" mode if I begin resizing windows memory consumption begins to rapidly rise (observed in System Monitor) and very quickly begins dumping into the swap space. As this happens the system naturally becomes very sluggish as the hard drive is written too. Once I stop resizing windows and wait for the writes to swap space to finish the systems performance goes back to normal but as soon as I resize a window again the swap space usage increases again and thus slows the system down once again. Currently as I write this my swap space is at 1.2gb of 2gb used and shows no sign of stopping if I resize a window. It would probably use all my memory if I kept resizing application windows (happens with any app I tested) but I'm reluctant to test that theory as it would probably crash my system. The other resize modes do not cause this leak.
I have tested with Metacity with its composite turned on and I get no such issue. Memory usage remains as expected.
This is on a Sony Vaio CR laptop with an Intel x3100 gpu. I have also seen similar but not quite the same issue using a Radeon 9700 (r300) gpu. With that system however no memory leak occurs but after resizing the windows a few times window performance becomes extremely slow (and does not return to normal where as the Intel does). So I do not think it is quite the same bug so will probably open a report for that issue as well.
I have also tested both systems using todays daily live cd (downloaded 16/04/2010 8:46am) on a usb stick and the same issue still occurred.
I will be able to test another laptop with an Intel 4500HD GPU later today using a live usb so will report back on how that turned out.

Should probably have mentioned that this issue was not occurring a couple weeks ago (on either the Intel or Ati gpu) but started once I updated the systems on Sunday (Apr 11) I think. It does not occur on Karmic either.
