Compiz blur doesn't work at all (Precise)

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version.

Gaussian blur still doesn't work. The other two blur options create strange effects in window shadows where you can see the desktop somehow vertically mirrored (see screenshot).

Hm, I wonder if your video driver doesn't play nicely. What video card/driver are you running? I've tried on an nvidia+binary and intel computer with no problem.

Onboard Intel 45GM graphics. In the past (Lucid) blur worked as desired.

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

Same here. I'm using a NVIDIA 7600GT and tried several driver-versions.
Blur does not work at all. Besides I have problems with a black screen after resume from suspend or hibernation - don't know if there could be any correlation.

I seem to have fixed it for myself--I have an nvidia 8600M GT, with two
monitors. I *think* what I did was install the NVIDIA-Linux-x86-295.53.run
driver, but it might have been the devdriver_4.2_linux_32_295.41.run one.
I'm pretty sure I'm not using Noveau or anything downloaded through the
"Additional Drivers" dialog, since every kernel upgrade seems to break my
graphics.

For me, however, there wasn't even an option for blur in CCSM's Effects
category, until I installed the driver downloaded from nvidia.
