** Description changed: Hello, I use in multiboot Ubuntu and Archlinux, I had the opportunity to use many kernels and I notice a random display problem (see screenshot) that happens from time to time on my Dell XPS but only from kernel 5.2 (and following). Under Ubuntu 19.04 with the 5.0 kernel I don't have this problem, under Archlinux with the old kernels (4.19LTS, 5.0, 5.1) I didn't have this problem either. But since 5.2 whether it is under Ubuntu or Archlinux, I have noticed this problem which is difficult to describe, it is a kind of band that appears at the top of the screen with a different size (sometimes very wide). The problem occurs randomly, sometimes it can go 30 minutes without seeing it appear and sometimes it can appear full of times for a few minutes. The problem is not specific to Ubuntu but to the kernel since 5.2 and following. Under the 19.10 of Ubuntu in development with the 5.3 kernel, the problem is still present. Could you please forward this bug to the team that deals with the linux kernel. (the 2 screenshots were taken under Ubuntu 19.10 with the 5.3 kernel but under Archlinux it's the same thing. Configuration : Dell XPS 13 model 2019 (9380) Graphics chipset: Intel® UHD 620 (Whiskey Lake 3x8 GT2) Noted that this problem can occur regardless of the activity on the desktop (browser, video player...), sometimes the screen skips completely for a tenth of a second. Please correct the problem quickly capture1: https://nsa40.casimages.com/img/2019/09/17/190917050728230823.jpg capture2: https://nsa40.casimages.com/img/2019/09/17/190917050801231741.jpg + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu7 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: simon 22176 F.... pulseaudio + /dev/snd/pcmC0D0p: simon 22176 F...m pulseaudio + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 19.10 + InstallationDate: Installed on 2019-07-18 (60 days ago) + InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) + MachineType: Dell Inc.
