apport information ** Tags added: reproducible ubuntu
** Description changed: Since sna acceleration of the intel display driver is enabled by default, I see two types of display distortions from time to time: i) windows have some times stippled borders, ii) xfce4-terminal shows distortions, when switching windows with alt+tab (view attachment). To reproduce it, open two terminals run some commands to fill them with text and switch between them via alt+tab a few times. I've found following workarounds to prevent this from happening: - switch to uxa via xorg.conf or - disable compositing in xfwm4 - replace xfwm4 with another wm (tested with mutter, metacity) Details: Mobile 4 Series Chipset Integrated Graphics Controller (rev 7) xserver-xorg-video- intel: 2.21.6-0ubuntu4 xfwm4: 4.10.0-4ubuntu1 xfce4-terminal: 0.6.1-0ubuntu2 --- ApportVersion: 2.12.7-0ubuntu3 Architecture: amd64 CasperVersion: 1.336ubuntu1 CurrentDesktop: XFCE DistroRelease: Ubuntu 14.04 LiveMediaBuild: Xubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140107) MarkForUpload: True Package: xserver-xorg-video-intel 2:2.99.907-0ubuntu1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 3.12.0-7.15-generic 3.12.4 Tags: trusty Uname: Linux 3.12.0-7-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + --- + ApportVersion: 2.13.1-0ubuntu1 + Architecture: amd64 + CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' + CompositorRunning: None + CurrentDesktop: XFCE + DistUpgraded: Fresh install + DistroCodename: trusty + DistroRelease: Ubuntu 14.04 + DistroVariant: ubuntu + ExtraDebuggingInterest: Yes + GraphicsCard: + Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) (prog-if 00 [VGA controller]) + Subsystem: Lenovo Device [17aa:2112] + Subsystem: Lenovo Device [17aa:2112] + InstallationDate: Installed on 2014-01-11 (0 days ago) + InstallationMedia: Xubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140107) + MachineType: LENOVO 2767WSD + Package: xserver-xorg-video-intel 2:2.99.907-0ubuntu1 + PackageArchitecture: amd64 + PccardctlIdent: + Socket 0: + no product info available + PccardctlStatus: + Socket 0: + no card + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-1-generic root=UUID=aaef342f-8a39-4660-b8fd-c1fe9349d82a ro quiet splash + ProcVersionSignature: Ubuntu 3.13.0-1.16-generic 3.13.0-rc7 + Tags: trusty ubuntu reproducible + Uname: Linux 3.13.0-1-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + dmi.bios.date: 10/17/2012 + dmi.bios.vendor: LENOVO + dmi.bios.version: 7UET94WW (3.24 ) + dmi.board.name: 2767WSD + dmi.board.vendor: LENOVO + dmi.board.version: Not Available + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: Not Available + dmi.modalias: dmi:bvnLENOVO:bvr7UET94WW(3.24):bd10/17/2012:svnLENOVO:pn2767WSD:pvrThinkPadT400:rvnLENOVO:rn2767WSD:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: + dmi.product.name: 2767WSD + dmi.product.version: ThinkPad T400 + dmi.sys.vendor: LENOVO + version.compiz: compiz N/A + version.ia32-libs: ia32-libs N/A + version.libdrm2: libdrm2 2.4.50-1 + version.libgl1-mesa-dri: libgl1-mesa-dri 10.0.1-1ubuntu2 + version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A + version.libgl1-mesa-glx: libgl1-mesa-glx 10.0.1-1ubuntu2 + version.xserver-xorg-core: xserver-xorg-core 2:1.14.5-1ubuntu2 + version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.8.2-1ubuntu1 + version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.2.0-0ubuntu10 + version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.907-0ubuntu1 + version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.10-1ubuntu1 + xserver.bootTime: Sat Jan 11 13:41:34 2014 + xserver.configfile: default + xserver.errors: + + xserver.logfile: /var/log/Xorg.0.log + xserver.outputs: + product id 16438 + vendor LEN + xserver.version: 2:1.14.5-1ubuntu2 ** Attachment added: "BootDmesg.txt" https://bugs.launchpad.net/bugs/1171411/+attachment/3946133/+files/BootDmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1171411 Title: xfwm4 may show display distortions, when using compositing on intel with sna To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1171411/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
