Title:
Display bug with kernel 5.2/5.3 on Dell XPS 13
Status in linux package in Ubuntu:
Incomplete
Bug description:
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
