Default Re: The productivity falls stronly after few work hours

Code:
Starting Xorg+KDE+Compiz

$ env __GL_FSAA_MODE=0 \
    __GL_SYNC_DISPLAY_DEVICE='DFP-0' \
    __GL_SYNC_TO_VBLANK=1 \
    compiz --replace ccp --ignore-desktop-hints --loose-binding 2>&1 &

$ nvidia-bug-report.sh 
$ mv nvidia-bug-report.log 1-nvidia-bug-report.log

$ LANG=C ; (date ;  vmstat -m | grep  nvidia)

       nvidia   816  3711K       -     2232  16,32,64,128,256,512,1024,2048,4096

$ glxgears
6901 frames in 5.0 seconds = 1380.188 FPS
6969 frames in 5.0 seconds = 1393.605 FPS
6948 frames in 5.0 seconds = 1389.464 FPS
Right after the system booting, all works well. But in course of time, the graphic system slows down.

The symptoms can be replicated:

It is possible to reproduce symptoms thus: it is necessary to activate "Water Effect" in Compiz on 30 minutes . After it, the graphic system does not restore the productivity

Code:
$ glxgears
6901 frames in 5.0 seconds = 1380.188 FPS
6969 frames in 5.0 seconds = 1393.605 FPS
6948 frames in 5.0 seconds = 1389.464 FPS

Turn on "Water Effect Plugin" in Compiz, and toggle "rain". (only for the repetition of the symptoms)

Turn off  "Water Effect Plugin" in Compiz

$ glxgears
689 frames in 5.0 seconds = 137.793 FPS
835 frames in 5.0 seconds = 166.987 FPS
770 frames in 5.0 seconds = 153.459 FPS
771 frames in 5.0 seconds = 152.894 FPS

$ nvidia-bug-report.sh
mv nvidia-bug-report.log 2-nvidia-bug-report.log

Maybe, that it related to the option "--loose-binding". But without this option Compiz works very badly permanently.
