I would be tempted to mark this as a duplicate of bug 888039 which was
fixed over the weekend. If you are interested, you can follow the thread
on that bug and test the fix. It seems to be working for me.

windows start to move slow after using compiz for some hours
To manage notifications about this bug go to:
compiz --replace works for me in that it gets rid of the window
slowness, but doing that causes the much more severe bug 903512 making
it impossible to switch workspaces without a complete graphics freeze,
so it's not really a fix.

Note there are problems with window movement even immediately after
logging in on some systems. That is covered by bug 773861 and bug

If I move a window with my mouse very fast around on my desktop no screen
updates happen.
My observation is that compiz has a high cpu usage, please see attached
screenshot (compiz high cpu usage).
Compiz has 70% and X has ~30% so in sum this are 100%.
I hope this can be fixed at least for
@Andrey Gladkyy:
How is this related to Bug #764330? In that bug, slowness always occurs and
only when mouse movement takes place.
In this bug, at least for me, slowdown occurs only after a long period
of time (days to weeks) and I experience lags when using the keyboard as
well; for instance,
Actually, it's related to

I don't think that these bugs are directly related to each other. The
main difference is that the windows only start to move really slow
after some time. For me it happens faster if I use my desktop more
active (many windows).

I've found a rather easy workaround. I simply had to disable the
following option in the Device section of my /etc/X11/xorg.conf (see the
attached file) so that vline doesn't wait for non-pageflipped swap
buffers:
Option SwapbuffersWait False
Remeber to restart the xserver afterwards (e.g. log
if I open many windows (e.g. 80 tabs in chromium + thunderbird and other
apps) things slow down a bit but not nearly as bad as it used to be.
I supposed it's the way the do sync to vblank in nux/compiz (?) which
reduces fps.

Ok, sorry for my English. I make some tests with miscellaneous compiz
configurations. On my nVidia GTX 260 (Gold series, 216 cores, offical
nvidia drivers) with enabled VBlank and refresh rate 120Hz (monitor
refresh rate x2) compiz works good until:
- run browser (Firefox). FPS when dragging
compiz --replace doesn't solve the problem in classic ubuntu desktop

H3ct0r: try doing Alt-F2, typing unity --replace without the quotes

I confirm running unity --replace in a terminal is a workaround to
solve the slowness problem. Thanks to Achim.

This happens every time I leave my computer and then come back, which
leads me to suspect that it happens whenever the monitor powers off,
also.

I've just reproduced the problem using Ubuntu's classic desktop (i.e.
only compiz), therefore I think this problem has very little to do with
Unity and might be a leak in compiz instead.

I can reproduce the problem with the r600c driver, so it's not nvidia
specific. Moving windows around makes CPU usage increase. This is with
an I-core 7 CPU with 6Gb of RAM.
According to the attached output of sysprof, libdecor.so and libcairo.so
play a big role in this issue.
