Blur not working

Hi, with 2.6.36-rc7|drm-radeon-testing and latest graphic stack snapshot kwin's 4.5.2 blur effect does not work. I have an HD3870, but someone else told me it works with RV710 (http://www.phoronix.com/forums/showthread.php?t=26221).

I attached a screenshot.

Comment 1 darkbasic 2010-10-07 15:34:36 UTC

I forgot to mention I use xorg 1.9.901.

Comment 2 Alex Deucher 2010-10-07 16:04:17 UTC

what version of mesa are you using and what is the screenshot supposed to be showing?  An error message?

Comment 3 darkbasic 2010-10-08 00:10:45 UTC

As I said latest snapshot, so mesa 7.10-devel.
The screenshot shows what I see instead of the blur effect: the window becomes dark gray.

I observe the same behavior RV730. What is more suprising, that I've seen exactly the same behavior on my friends computer who has nouveau gallium driver. Maybe FOSS drivers have not yet implemented some OpenGL functionality, i.e. insufficient GLSL support.

For the record, with blur correctly working it should look like this:

Somebody observed that blur effect is broken by the new glsl compiler, so this is not R600 bug.

Comment 8 Jerome Glisse 2011-02-09 07:29:55 UTC

Is it still broken ?

Comment 9 darkbasic 2011-02-09 08:39:54 UTC

I don't have kwin 4.5 anymore, I can test it with kwin 4.6 if you want but I think it will work because it does work even with intel (!).

Comment 10 darkbasic 2011-02-09 13:40:55 UTC

It does work with R600g and kwin 4.6.

RV670 with R600g, 2.6.38-rc4, xorg-server-1.9.4, mesa git, libdrm git, xf86-video-ati git, pageflipping on, colortiling on, swapbufferwaits off.

If you want you can close.
