Thank you for taking the time to report this issue and helping to make Ubuntu better.
If you change wallpapers, does the issue still occur? Does it occur if you have windows fullscreen (eg. if firefox is your open window and maximized so it covers your wallpaper, do you see the artifacts?) or are they visible only on your wallpaper? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1870725 Title: artifacts appearing on gnome shell Status in ubuntu-meta package in Ubuntu: New Status in xorg package in Ubuntu: New Bug description: problems appear on the desktop and lock screen (not in gdm) ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: xorg 1:7.7+19ubuntu14 ProcVersionSignature: Ubuntu 5.4.0-21.25-generic 5.4.27 Uname: Linux 5.4.0-21-generic x86_64 ApportVersion: 2.20.11-0ubuntu22 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Fri Apr 3 22:50:55 2020 DistUpgraded: 2020-04-03 20:26:10,751 ERROR got error from PostInstallScript ./xorg_fix_proprietary.py (g-exec-error-quark: Failed to execute child process “./xorg_fix_proprietary.py” (No such file or directory) (8)) DistroCodename: focal DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation UHD Graphics 620 [8086:5917] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Lenovo UHD Graphics 620 [17aa:225d] InstallationDate: Installed on 2020-03-30 (4 days ago) InstallationMedia: Ubuntu 18.04.4 LTS "Bionic Beaver" - Release amd64 (20200203.1) MachineType: LENOVO 20L5CTO1WW ProcEnviron: PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.4.0-21-generic root=UUID=9aa1adb4-3c73-4d9b-8968-83630fb790f2 ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to focal on 2020-04-04 (0 days ago) dmi.bios.date: 02/19/2020 dmi.bios.vendor: LENOVO dmi.bios.version: N24ET56W (1.31 ) dmi.board.asset.tag: Not Available dmi.board.name: 20L5CTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0K17763 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN24ET56W(1.31):bd02/19/2020:svnLENOVO:pn20L5CTO1WW:pvrThinkPadT480:rvnLENOVO:rn20L5CTO1WW:rvrSDK0K17763WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T480 dmi.product.name: 20L5CTO1WW dmi.product.sku: LENOVO_MT_20L5_BU_Think_FM_ThinkPad T480 dmi.product.version: ThinkPad T480 dmi.sys.vendor: LENOVO version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.100-4 version.libgl1-mesa-dri: libgl1-mesa-dri 20.0.2-1ubuntu1 version.libgl1-mesa-glx: libgl1-mesa-glx 20.0.2-1ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.20.7-2ubuntu2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:19.1.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20190815-1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.16-1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/1870725/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
