Compiz uses more CPU and mem since upgrading from 11.10

[autra]

since I upgrading to 12.04 Compiz uses a lot more CPU : it stays around 15-20% CPU.
The memory usage also increased dramatically, and now reaches 380Mo !!! It has never reached more than 200Mo before

Xorg also has increased memory usage : it uses now around 220 Mo.

I have the same problem with high CPU usage - ~15% idle, 35% when moving mouse. Running chromium on the background with some flash 55%.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Evren Yurtesen (eyurtese-g)]

I have exactly the same issue, moving the mouse makes compiz to use 50% CPU

[Mark Lassiter (mlassiter)]

This may be a different issue, but I can reproduce high CPU every time by doing the following:

1. Installed wine
2. Installed a game (DDO)
3. Run it (runs flawlessly)
4. Exit the wine application
5. compiz process immediately goes to 100% CPU and never comes back

A number of graphic anomolies riddle the desktop as well, rendering it virtually unusable, so at this point, after playing the game, my son is forced to reboot.

Please let me know if I can provide any more information, I would be happy to. I realize wine is in the mix, but hopeing that its making it easier to reproduce the issue.

Same problem here with a fresh install of Ubuntu 12.04. Compiz and Xord use a lot of CPU !

I've never been under 10% at idle without anything opened. (1-2% with 11.04)

I was running with 11.04 before and everything was perfect. I was playing a 720p video with VLC and my CPU was at about 30% max. Now with 12.04 Compiz itself uses something like 15% so that like 55/60 top CPU for the same video.... With flash, my CPU burn.

What's going on? My system is so slow now :(

@Mark Lassiter : I think you don't have the same issue. Our compiz is always quite high. Yours gets high only on wine closing and it stays at 100% (whereas we have only 10-15%). I think your problem is that wine does not properly quit after leaving the game. Have you tried to kill the processes of wine (wine.exe, winedevice, explorer.exe ?) after you son stopped playing ?
Otherwise, I would advise you to post a but report to wine website.

Guys, a workaround for that is of course to use Unity-2d... (but this is not great I know)
