I believed I narrowed down the issue to how gnome-shell uses Xorg. As said before GDM did not have any issues, and (i may be seriously wrong here) GDM uses Wayland by default. When I launch the Ubuntu desktop with Wayland, the graphical issue went away and is running smoothly.
So I narrowed down the issue to Xorg or gnome-shell. So I went ahead and installed Cinnamon DE which uses Xorg, and the issue did not arise. My theory is that gnome-shell has a problem with rendering the shell (not programs) with Xorg. I also attached another image showing the problem, could the issue be the compositor??? ** Attachment added: "Screenshot from 2020-04-04 13-11-46.png" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1870725/+attachment/5346554/+files/Screenshot%20from%202020-04-04%2013-11-46.png ** No longer affects: ubuntu-meta (Ubuntu) ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New -- 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 gnome-shell 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/gnome-shell/+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
