Public bug reported: Hi,
I'm running Ubuntu MATE 18.04.6 LTS. The bug information was sadly collected from the working configuration of the system after dropping to an earlier kernel. This bug is a display bug where 1-pixel horizontal lines of multicolored corruption or occasionally incorrect screen contents appear across the screen, particularly during scrolling or moving the mouse. They appear intermittently, being more common near the top of the screen. My GPU is the built-in one on the AMD A10-5750M APU, the Radeon HD 8650G. (Laptop: G505s) I have found that this bug occurs on vmlinuz-5.4.0-96-generic but does not appear to occur on vmlinuz-5.4.0-91-generic when booting with that option in GRUB. I have not yet been able to capture an image of the issue as it becomes difficult to use the system when the bug occurs (though it appears to be fully functional, graphics aside). If very important I can try again later. -Matt ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 5.4.0-91.102~18.04.1-generic 5.4.151 Uname: Linux 5.4.0-91-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.9-0ubuntu7.27 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: MATE Date: Thu Jan 20 14:05:30 2022 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu DkmsStatus: bcmwl, 6.30.223.271+bdcom, 5.4.0-91-generic, x86_64: installed bcmwl, 6.30.223.271+bdcom, 5.4.0-94-generic, x86_64: installed bcmwl, 6.30.223.271+bdcom, 5.4.0-96-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Advanced Micro Devices, Inc.
