On my notebook Toshiba U205 S5034 - with Intel VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03), I fix the performance issue by a change into xorg.conf:

Section "Device"
 Identifier "Configured Video Device"

 # It turns off disabling pipa A by a driver after while.
 # Its 100 % working workaround.
  Option "ForceEnablePipeA" "true"

 # restore COMPIZ performance
 Option "AccelMethod" "UXA"

 # Option "FramebufferCompression" "off"
EndSection
