[Solved] Blender and issues with libpng & with NOUVEAU dri.

Hi all!!! It's my first post here! I'm using archlinux by few months. Two days ago, after I updated my system, Blender began to work not well.

First, as shown in the image, it doesn't show me the whole 'welcome' image.

Second, as shown in the image, when I run a render, it doesn't show me the whole result, but only few parts.

When I run blender from command line it returns me this warning/error:

libpng warning: iCCP: known incorrect sRGB profile

Someone suggested me to use 'optipng' to all png used by blender.
I applied it on all png found with

pacman -Ql blender | grep png 

, but the result is the same.

Any idea??

Sorry for my english!!

Byeeee

I guess you need to recompile Blender since the last libpng upgrade.

@neodreams

The package 'blender' is in the official repos, and has been built since the libpng upgrade.

@piter85
Make certain you have the most up to date version of blender. You can also check the libpng version needed by blender by running

ldd /usr/bin/blender | grep png

HI!
The blender version is the last (2.67)

The command returns me :

ldd /usr/bin/blender | grep png
	libpng16.so.16 => /usr/lib/libpng16.so.16 (0xb7680000)

The versione of libpng that is installed on my system is :

local/libpng 1.6.2-3

Any idea??

Re: [Solved] Blender and issues with libpng & with NOUVEAU dri.

Hi!  Someone on blender IRC channel shows me that this issue are about graphic drivers. In fact, in the portable version of blender there's a script called 'blender-softwaregl' that use a software implementation OpenGL to draw. Using this script blender works well, so graphic drivers are responsible for these issues.

Now, my graphic drivers are 'xf86-video-nouveau'.  Any idea on how resolve these issue??

P.S. During the famous update, also graphic drivers has been updated.
