Compiz proces is always using too much cpu.

Some examples:
- When I use ALT+F2 and I type something compiz uses 170% cpu.
- When I use ALT+TAB compiz uses 120% cpu.
- While I'm writing this text compiz is using 30% cpu
- My system running only a terminal with top but compiz using 12% cpu

Hi,
After upgrading compiz to 1:0.9.11+14.04.20140328-0ubuntu1, important improvements to solve this have been achieved.

Thanks.

Hi,
After installing several Ubuntu trusty I must tell you that this problem could be due to the graphic card driver (nouveau).

I have tried this release with others PC and compiz works fine, so I think that my problem could be related with my graphic card (NVIDIA Corporation G72 [GeForce 7200 GS / 7300 SE] (rev a1))

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

[Alberto Salvia Novella (es20490446e)]

It renders the system temporarily or permanently unusable.

[Mau (maugarta-cc)]

It renders permanently very slow and glxinfo shows 'OpenGL vendor string: VMware, Inc.'

I don't have vmware softare intalled and this is not a virtual machine.

#glxinfo | grep -i string
server glx vendor string: SGI
server glx version string: 1.4
client glx vendor string: Mesa Project and SGI
client glx version string: 1.4
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits)
OpenGL version string: 2.1 Mesa 10.1.0
OpenGL shading language version string: 1.30

I think this bug is like

I have recently installed Ubuntu 14.04 LTS. It worked wonderfully at first, but then it started to be extremely slow to open and close new windows. The system monitor showed that the processor ran at around 100% although I was nothing special. The "Compiz" process took up around 40% of the processor power.

The problem started a while after I had connected an external monitor. First it worked wonderfully, but after a while the problems started. Maybe there is some problem with compiz that arises when one uses an external monitor. Maybe compiz has a but that is triggered when the graphics-processor sending data to an external monitor.

The problem did not disappear immediately when I deselected the external monitor. I restarted but it was still there, but when I started the computer today it worked OK. I do not dare to connect the external monitor again because I do not want to be stuck with the same problem again. I have a Dell U2311H with 1920 × 1080 pixels, while the laptop has 1280 × 800 pixels.

[Christopher Townsend (townsend)]

I don't think this is a Compiz problem, but is probably a problem in Mesa which is incorrectly selecting the software renderer as the display driver. When this happens, the CPU is used exclusively for all OpenGL calls which makes Compiz use a great amount of CPU. Nothing we can do about that.

As such, going to dup this to bug #1268146.

[Xi (tracytsang-whu)]

I have the same problem with Kalle (jessica-2)
When using second monitor the compiz and Xorg processes eating too much CPU
