** Description changed: - When using apps where client-side decorations are being used, a strange - shadow render appears below the window. Screenshots are attached. If - CSDs are not being used, then shadows are rendered correctly. + [Impact] + The Intel video driver has a bug that can cause to incorrectly draw certain trapezoids. This is visible when using client side decorations in GNOME 3 (see attached screenshots). - WORKAROUND: Remove the GNOME3 Staging PPA. + [Test Case] + Run GNOME 3 with client side decorations on Intel hardware. + Observed result: + Shadow under window is missing corners. + Expected result: + Shadow looks correct. - ProblemType: Bug - DistroRelease: Ubuntu 14.10 - Package: mutter 3.14.0-1ubuntu1~utopic1 [origin: LP-PPA-gnome3-team-gnome3-staging] - ProcVersionSignature: Ubuntu 3.16.0-20.27-generic 3.16.3 - Uname: Linux 3.16.0-20-generic x86_64 - ApportVersion: 2.14.7-0ubuntu3 - Architecture: amd64 - CurrentDesktop: GNOME - Date: Mon Oct 6 22:50:17 2014 - InstallationDate: Installed on 2014-06-13 (115 days ago) - InstallationMedia: Ubuntu-GNOME 14.04 LTS "Trusty Tahr" - Release amd64 (20140416.2) - ProcEnviron: - TERM=xterm - PATH=(custom, no user) - XDG_RUNTIME_DIR=<set> - LANG=en_US.UTF-8 - SHELL=/bin/bash - SourcePackage: mutter - UpgradeStatus: Upgraded to utopic on 2014-10-03 (3 days ago) - --- - ApportVersion: 2.14.7-0ubuntu8 - Architecture: amd64 - CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' - CompositorRunning: None - CurrentDesktop: GNOME - DistUpgraded: 2014-10-03 08:48:19,347 DEBUG enabling apt cron job - DistroCodename: utopic - DistroRelease: Ubuntu 14.10 - DistroVariant: ubuntu - DkmsStatus: - vboxhost, 4.3.16, 3.13.0-35-generic, x86_64: installed - vboxhost, 4.3.16, 3.16.0-20-generic, x86_64: installed - vboxhost, 4.3.16, 3.16.0-21-generic, x86_64: installed - vboxhost, 4.3.16, 3.16.0-25-generic, x86_64: installed - ExtraDebuggingInterest: Yes, if not too technical - GraphicsCard: - Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display [8086:0f31] (rev 0c) (prog-if 00 [VGA controller]) - Subsystem: Acer Incorporated [ALI] Device [1025:0845] - InstallationDate: Installed on 2014-06-13 (171 days ago) - InstallationMedia: Ubuntu-GNOME 14.04 LTS "Trusty Tahr" - Release amd64 (20140416.2) - MachineType: Acer E1-510P - Package: xorg 1:7.7+7ubuntu2 - PackageArchitecture: amd64 - ProcEnviron: - TERM=xterm - PATH=(custom, no user) - XDG_RUNTIME_DIR=<set> - LANG=en_US.UTF-8 - SHELL=/bin/bash - ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-25-generic.efi.signed root=UUID=87cb643d-4e85-4be4-9864-0e13b0ed0382 ro quiet splash acpi_osi=Linux i915.invert_brightness=1 vt.handoff=7 - ProcVersionSignature: Ubuntu 3.16.0-25.33-generic 3.16.7 - Tags: third-party-packages utopic gnome3-ppa ubuntu - Uname: Linux 3.16.0-25-generic x86_64 - UpgradeStatus: Upgraded to utopic on 2014-10-03 (59 days ago) - UserGroups: adm cdrom dip libvirtd lpadmin plugdev sambashare sudo vboxusers - _MarkForUpload: True - dmi.bios.date: 04/07/2014 - dmi.bios.vendor: Acer - dmi.bios.version: V2.11 - dmi.board.name: E1-510P - dmi.board.vendor: Acer - dmi.board.version: V2.11 - dmi.chassis.type: 10 - dmi.chassis.vendor: Acer - dmi.chassis.version: Chassis Version - dmi.modalias: dmi:bvnAcer:bvrV2.11:bd04/07/2014:svnAcer:pnE1-510P:pvrV2.11:rvnAcer:rnE1-510P:rvrV2.11:cvnAcer:ct10:cvrChassisVersion: - dmi.product.name: E1-510P - dmi.product.version: V2.11 - dmi.sys.vendor: Acer - version.compiz: compiz N/A - version.ia32-libs: ia32-libs N/A - version.libdrm2: libdrm2 2.4.56-1 - version.libgl1-mesa-dri: libgl1-mesa-dri 10.3.0-0ubuntu3 - version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A - version.libgl1-mesa-glx: libgl1-mesa-glx 10.3.0-0ubuntu3 - version.xserver-xorg-core: xserver-xorg-core 2:1.16.0-1ubuntu1 - version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.9.0-1ubuntu2 - version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.4.0-2ubuntu2 - version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.914-1~exp1ubuntu4.1 - version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu2 - xserver.bootTime: Mon Dec 1 22:16:33 2014 - xserver.configfile: default - xserver.errors: - - xserver.logfile: /var/log/Xorg.0.log - xserver.outputs: - product id 4588 - vendor AUO - xserver.version: 2:1.16.0-1ubuntu1 + [Regression potential] + Low.
