Description Patrizio Bassi 2011-07-16 07:33:00 UTC 
I'm using linux 2.6.39.3 with nouveau kms driver on a geforce 7600GT
X.Org X Server 1.10.3
xf86-video-nouveau-0.0.16_pre20110711 (but with march's snapshot is the same)

switching from mesa 7.10.3 to 7.11_rc1 makes taxt not really clear and colors are messed up as from screenshot.

i tried with egl and llvm flags and without, same result.

just reverting to 7.10.3 make everything fine.

It looks like some RGB color swap. You are using compositing, yes? Does this happen with mesa-9999 from the x11 overlay too?
Comment 3 Patrizio Bassi 2011-07-17 08:14:53 UTC 
i do use kwin's compositing.

Actually as you can see it's not all RGB colors broken, just some. I tought it was svg stuff only so i tried with or without openvg flag. no change.

Didn't tray overlay's, not yet at least.

quite bad because this rc1 seems to fix some issues with chromium webgl init failures.

anyhow there is the problem with aliasing too, Konsole fonts are quite foggy bu readable, GTK apps look better
Comment 4 Chí-Thanh Christopher Nguyễn gentoo-dev 2011-07-17 08:17:12 UTC 
Fonts might look bad because colors are used for subpixel hinting, and if the colors are wrong then the hinting will be bad.
Comment 5 Patrizio Bassi 2011-07-17 08:47:57 UTC 
tried 9999 today's live git

same issues of 7.11_rc1.
reverted to 7.10.3

It is probably a good idea if you report it upstream on bugs.freedesktop.org, so that nouveau developers are aware of the problem. You can add the bug URL to this bug so we can see whether it is feasible to backport any patches.

patch is at http://lists.freedesktop.org/archives/mesa-dev/2011-July/009563.html

While waiting for upstream to release a new rc or final version, can you please apply the patch to portage tree?

I have tried and it works flawlessy

Please open a new bug if the font issue still exists.
