Bug Description

Binary package hint: compiz

OS:
Ubuntu 11.04
compiz:
1:0.9.4+bzr20110415-0ubuntu2
Windows decorator: Matacity

In compiz config window enabled Blur, and have next settings:
pulse = False
blur_speed = 3.5
focus_blur_match = "toolbar | menu | utility | normal | dialog | modaldialog"
focus_blur = False
alphs_blur_match = "any"
alpha_blur = True
filter = "Gaussian"
gaussian_radius = 15
gaussian_strength = 1.0
mipmap_lod = 2.5
saturation = 100
occlusion = True
independent_tex = False or True (in any case I get bug)

From this moment shadows of windows also have blur, but sometimes in shadow, permanently or for a moment, appear ghost image (see attachment screen.jpg). To get it - window maybe must be moved over another window.

I'm affected by the bug as well. The only difference in the compiz settings is the gaussian_radius, which is 4 in my case (instead of 15). I don't know if it matters, but I have a nVidia GeForce 8600M GS with proprietary drivers.

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. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on your current version. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at ubuntu.com). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. If you are unable to test the development version, please let us know if you are able to reproduce this issue on Ubuntu 11.10.

Thank you for your help and patience.

I check this in Ubuntu 12.04 with enabled Mipmap blur (because gaussian blur don't work anymore)
And still have this problem. See attached screenshot.

It seems like the blur plugin sees the shadow as part of the window decorator and tries to blur the background of it.
