Screenshot taken with import after opening a new tab in Iceweasel 17.0.8
Using Debian Wheezy with
linux-image-3.2.0-4-686-pae 3.2.46-1+deb7u1
xserver-xorg-video-nouveau 1:1.0.1-5
libglu1-mesa:i386 8.0.5-4+deb7u2
libdrm2 2.4.40-1~deb7u2
libudev0 175-7.2
xserver-xorg-core [xorg-video-abi-12] 2:1.12.4-6
sometimes there is an image corruption where some areas are garbled with other colors. See the attached screenshot taken with import from the ImageMagick suite. (What is that type of corruption called?)
The obfuscation was done with the following command.
$ convert 20130909-Debian_Wheezy-nouveau-corruption.png -draw "rectangle 231,165 1703,953" 20130909-Debian_Wheezy-nouveau-corruption--obfuscated.png
This issue happened five times and I do not know how to force it. Three of these five times it happened after resuming from suspend to RAM. Additionally after these corruption start, the system is going to freeze after some time. There are no error messages in /var/log/syslog, /var/log/messages, /var/log/Xorg.0.log and ~/.xsession-errors.
Please tell me, what else you need for debugging.
