Prasanna Kumar, thank you for reporting this and helping make Ubuntu better.
As per https://wiki.ubuntu.com/Releases, Ubuntu 11.10 reached EOL on May 9, 2013. Is this reproducible on a supported release? ** Changed in: mesa (Ubuntu) Importance: Undecided => Low ** Changed in: mesa (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/901815 Title: Random image getting rendered in intel i945G graphics card Status in mesa package in Ubuntu: Incomplete Bug description: Random image is rendered when I am doing normal work (like reading documents, web surfing, etc) with gnome 3 running. I am using ubuntu 11.10 64bit version. When I run gnome 2 (ubuntu classic without effects) no artifacts are there. When running gnome 2 (with compiz enabled) I am getting similar effects. Guess this to be related to OpenGL Mesa package. I am having a Intel 82945G/GZ graphics card. Mine is a fresh installation of ubuntu 11.10. My system is up to date. Output of certain commands that may be helpful: lspci: 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) dmesg | grep drm: [ 19.370851] [drm] Initialized drm 1.1.0 20060810 [ 19.553129] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

I guess it is because of OpenGL driver (mesa) as running gnome3 (mutter) also has the same effect.
