Title:
[Dell XPS 13 9380] PSR causes screen flickering
Status in linux-hwe-5.11 package in Ubuntu:
Triaged
Bug description:
Hello!
After the upgrade to the 5.8 series kernel to the 5.11 series kernel,
I have noticed some screen flickering. I had the same problem
previously on Fedora after upgrading to the 5.0 series kernel, but
this was not present on Ubuntu 20.04 on either the 5.4 or 5.8 series
kernels. On Fedora, it was fixed by turning off panel self-refresh on
my Dell XPS 13 9380. I can try that again here if you all think it
would be a useful piece of information. In the Fedora bug, it was
reported that this problem is fixed in the 5.13 kernel. Let me know
whatever else I can do.
Thanks!
Ben
