White-out icons screenshot

Description of problem: After applying the latest updates last Friday, which includes gnome-shell-2.91.92, the icons under Applications in the overview mode became white washed as shown in the attached screenshot. 
I noticed xorg-x11-drv-nouveau update was also in the mix of the updates, but dowgrading xorg-x11-drv-nouveau with yum doesn't bring back the nice icons.

Comment 1 Owen Taylor 2011-03-28 15:43:37 UTC
Probably triggered by the GLSL code change to fix the affected shader to work on R300:

http://git.gnome.org/browse/gnome-shell/commit/?id=43cf60f5636e7883bd5012e4c89ed5d57e28200c

Comment 2 Deji Akingunola 2011-03-28 15:56:38 UTC
As an additional information, System-Info on gnome-shell say my driver is 'Gallium 0.4 on NV94'

Comment 3 Adam Williamson 2011-03-29 18:18:30 UTC
Confirmed here. Note that when you select any particular category, the icons are fine; it's only with 'All' selected that you get the whitewash effect.

proposing NTH for Beta as it's a very visible polish issue.

Comment 4 Owen Taylor 2011-03-29 18:23:45 UTC
The reason it only happens with All selected is that the shader is only active when the area is scrolled - the function of the shader is to add a "fade out" effect at the edges of the scrolled area.

Comment 5 Ben Skeggs 2011-03-29 20:54:01 UTC
Can you retry with http://koji.fedoraproject.org/koji/buildinfo?buildID=236413 please?

Comment 6 Deji Akingunola 2011-03-29 21:09:01 UTC
mesa-dri-drivers-7.11-0.1.20110327.0.fc15.x86_64 doesn't make any difference to the issue, the whitewash icons are still present.

Comment 7 Adam Williamson 2011-03-30 00:36:39 UTC
with the full set of new mesa packages installed and a reboot, it's still broken.

Comment 8 Paul W. Frields 2011-03-30 00:43:07 UTC
Same results here: http://pfrields.fedorapeople.org/temp/shell-20110329-1.webm
(Just because I love the screencast recorder.)

Comment 9 Paul W. Frields 2011-03-30 00:44:53 UTC
Ugh, entered too early:

01:00.0 VGA compatible controller [0300]: nVidia Corporation G86 [GeForce 8400M GS] [10de:0427] (rev a1)
Shell system info reports: Gallium 0.4 on NV86 

+1 NTH on Beta, even though my vote doesn't count. ;-) Happy to hear we might know the cause of the problem in any case.

Comment 11 Paul W. Frields 2011-03-31 14:52:56 UTC
Still the case with:

mesa-dri-drivers-7.11-0.3.20110330.0.fc15.x86_64
xorg-x11-drv-nouveau-0.0.16-24.20110324git8378443.fc15.x86_64
gnome-shell-2.91.93-3.fc15.x86_64
mutter-2.91.93-1.fc15.x86_64

Sorry I'm not too clueful about which of those is most important in this case.

Comment 17 Tim Flink 2011-04-01 20:38:14 UTC
Discussed during the 2011-04-01 blocker bug review meeting. This is a pretty obvious polish issue for the people that hit it. Accepting as NTH.

Fix has been submitted, need more testing to determine status.

Comment 18 Fabien Archambault 2011-04-02 08:37:15 UTC
The update of mesa-dri-drivers-7.11-0.5.20110401.0.fc15.x86_64 solves the issue for me.
Using nouveau on a GeForece 8400M GS.

Comment 19 Ionut Biru 2011-04-02 09:30:19 UTC
any of you know what commits fix the problem? I'm interested to apply it on mesa 7.10.1

Comment 20 Paul W. Frields 2011-04-02 20:43:11 UTC
This issue is fixed for me too with the update in comment 18.  Link:

The commit which fixes it will not apply on 7.10, the nv50 3D driver was completely replaced post-7.10.

The issue has been fixed for me too. Closing.
