Whenever I am watching a video, on any of my displays (laptop, or 2 external), there is a screen tear in the middle of the screen. I have never experienced this before while I was using 18.04, and it started immediately after installing 20.04. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: lance 1482 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-04-24 (11 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) MachineType: LENOVO 20HDCTO1WW Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.4.0-28-generic root=UUID=8968c86c-f827-46b8-8aee-0434135ba0df ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.4.0-28.32-generic 5.4.30 RelatedPackageVersions: linux-restricted-modules-5.4.0-28-generic N/A linux-backports-modules-5.4.0-28-generic N/A linux-firmware 1.187 Tags: focal Uname: Linux 5.4.0-28-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 02/27/2020 dmi.bios.vendor: LENOVO dmi.bios.version: N1QET87W (1.62 ) dmi.board.asset.tag: Not Available dmi.board.name: 20HDCTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0J40709 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN1QET87W(1.62):bd02/27/2020:svnLENOVO:pn20HDCTO1WW:pvrThinkPadT470:rvnLENOVO:rn20HDCTO1WW:rvrSDK0J40709WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T470 dmi.product.name: 20HDCTO1WW dmi.product.sku: LENOVO_MT_20HD_BU_Think_FM_ThinkPad T470 dmi.product.version: ThinkPad T470 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1876980/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
