compiz + nvidia anti-aliasing = problems with opacity and shadows (several blinking effects).

Bug #279571 reported by ®om on 2008-10-07
Affects Status Importance Assigned to Milestone

Bug Description

If in nvidia-settings, antialiasing is enabled, compiz has some problems with opacity and shadows (several blinking effects).

Please watch the attached video (mkv-x264), that I made in february to post in nvidia forums :

But no news :(

I open a bug report here to keep trace of this problem.

Maybe something in compiz could avoid it?

This problem doesn't occur when Benchmarking plugin is enabled !

Hi rom1v,

Please attach the output of `lspci -vvnn` too.

The bug is related to
(as enabling benchmaring resolves both vsync and antialiasing problems)

Odd, I only see these black and thickening drop-shadows, when I've the blur-plugin enabled. Otherwise I can use antialiasing with compiz. I'm running a GeForce 8800 GTS on nvidia's binary 177.82 driver.

In Jaunty (9.04) we have dropped the nvidia-graphics-driver-177 package, as
it is superseded by nvidia-graphics-drivers-180.

Because of this, we are closing this bug as expired.

You are encouraged to file your -nvidia bug reports against the
nvidia-graphics-drivers-180 package. Please be aware that because this
is a proprietary graphics driver, the amount of bug support we can
provide at the distro level is very limited.
