compiz fusion reflection & blur windows plugins broken?

[sancho panza]

Is the compiz fusion reflection and motion blur plugin workin well with all? In my case, the reflection plugin just greys out the current window and the blur plugin greys out all the background windows.
The rain plugin doesn't work either, but that is not my favorite anyways.

Anybody?

Does everyone else have those effects working?
Bump...

[exilist]

Yes and No.

Yes it worked on my pc with nvidia card.

And no it don't work on my latop: INTEL i910 graphics.

Maybe the INTEL driver doesn't support necessary features.

Yep, I have not been able to achieve any blur effect either :(

This is with a Radeon 9600 Pro and the open ATI driver.

All those plugins require your card to support pixel shader programs of at least a certain length, and neither the radeon 9600 nor the Intel cards support long enough shader programs.

It would be better if compiz detected this and refused to enable them, rather than having rendering artifacts however. Feel free to file a bug, although it (probably) won't be fixed before Gutsy releases at this point.

[Mr. Picklesworth]

Fair enough, but I must ask: How big is this shader program? The 9600 can handle some fairly significant shaders, so I find it odd that a blurring algorithm could pose such a problem.

Thanks, RAOF!

I find it surprising that even the latest integrated graphics cards (intel 965) are uncapable of handling gutsy. Do the users need to have a dedicated graphics card just to run the window manager? Thats unfair!
I dont know about pixel shaders, but is there no workaround? Or is that why you suggested filing a bug report?

Cheers!

No, but they do need a fairly powerful graphics card to run the (optional) intensive features, such as blur. Relatively recent ATI and nVidia integrated cards support the necessary stuff to make blur work, Intel cards don't.

@Mr. Picklesworth: There's actually a bit of overhead here due to the Compiz infrastructure required to make multiple shaders work together properly. Intel & older ATI cards used to be able to do the pre-fragment-program-interface blur, but the overhead in the code added to allow multiple shaders to co-exist peacefully pushed the fragment program over the limit.
