If the workaround at the top of this bug and my PPA do not solve the

worth a try.
Please also confirm the version you're testing from ppa:vanvugt/compiz.
Experimental fixes for this and related performance bugs are now available
for testing in ppa:vanvugt/compiz and ppa:vanvugt/unity. For the best
results I recommend trying both together. But testing them individually is
useful too.

@Daniel and Chauncellor:
I seem to have exactly the same problems mentionned by Chauncellor :

x86_64)
- Problem only affects moving windows around and dragging icons.

@Chauncellor...
If disabling DynamicTwinView didn't work for your nvidia system, try setting
this in CCSM:
Detect Refresh Rate = OFF
Refresh Rate = the real refresh rate of your monitor, maybe even higher.
If that still doesn't work then you are not experiencing bug 92599. But read
on...
Sorry, I performed some other tests and they proved I was wrong with
bailer.
Now it seems that the situation can be simply improved by deactivating
the FPS detection, and forcing the framerate to 120Hz. In this way the
performance is acceptable.
However, now I'm writing from gnome-shell, and
Yes, this bug is something we can work around in compiz, as you found by
changing the frame rate. I suggest it is also possible to improve the
compiz code so that it avoids the issue and also avoids the need for a
very high frame rate. But wait and see, if and when I (or someone else)
has the time
Tried the TwinView workaround and lightdm won't even load. Tried
manually setting the refresh rate in ccsm and there is no appreciable
change. Turning off bailer also does nothing. Seems to be some sort of
leak because at startup or compiz restart everything works smoothly. 2
minutes later and the
Deactivating Bailer and increasing the refresh rate do improve, but
don't completely fix the problems. glxgears is smoother, but still
jerks noticeably from time to time and gets much smoother as the window
size increases. And moving and resizing windows is still much, much
slower than with
That's excellent news. Please create a new bug titled something like:

It's good news because it sounds like we're just dealing with a logic
problem, or frame deadline problem, in compiz.
Instead of disabling Bailer
same problem here, deactivating bailer and forcing the framerate to 120Hz (my
monitor goes 60Hz) did the trick.
