Can we identify which package is the culprit? i.e. purge the ppa then just install xserver-xorg-video-intel, then install libgl1-mesa-dri, testing after each step to see when the bug is introduced. The problem appeared when I upgraded libgl1-mesa-dri from 8.0.2 to 8.1~git20120501.2d75a1e2 from the xorg-edgers PPA. I have reassigned this bug to Mesa:Server/Ext/DRI. Please reassign if this isn't correct. This has been verified on ubuntu too, see https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1042211 bottom line: mesa 8.0.4 works, 9.0~ doesn't The Mesa 10 and 9 suffers from white-stripes corruption in KDE4.8.4 and 4.11. The resolution is to downgrade to Mesa 8, but it is not avaliable in Ubuntu 14.04. I think the problem with mesa is still here. Found in Ivy bridge and Sandy bridge.

Very little active work is happening on the i915 driver. Is there any chance of getting an 8.0.4 to 8.1 bisect? Without that, there's fairly little probability of this getting fixed... As the reporter of this bug, I no longer have access to the i915 laptop for testing, so I'm afraid I won't be able to provide any more info or testing. Anybody else? (In reply to S.

Thank you for your time Christian, it seems that no more updates on the case were provided in a long time. Closing. |

Created attachment 60981 [details] Xorg log file I am running Kubuntu 12.04, and after upgrading to the packages in the xorg-edgers PPA, some OpenGL elements are no longer rendered correctly. Among the package upgrades were: . xserver: 1.11.4 -> 1.12.1+git20120502+server-1.12-branch.ed33772a . xserver-xorg-video-intel: 2.19.0 (x-updates PPA) -> 2.19.0+git20120501.7e09babb The rendering bug can be seen with GLX-dock. I have attached a comparison screenshot where you can see the dock reflections are incorrect. and the icon below the one with focus disappears. ** My System ** OS: Kubuntu 12.04 i386 w/ KDE SC 4.8.2 PC: HP Pavilion dv1550se laptop CPU: Intel(R) Pentium(R) M processor 1.60GHz RAM: 1.5GB DDR400 Video: Mobile 915GM/GMS/910GML Express Graphics Controller Sound: 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller Linux Kernel: 3.2.0-24-generic Screen Resolution: 1280 x 768
