It looks like one of the recent Linux kernel updates is causing issues with Intel laptops. Apparently the 5.19.12 update is not playing nice with Intel's graphics i915 driver and this is leading to all sorts of issues. For example, below is an example of a user who said that they were almost constantly encountering weird flashing problems. The user added they had the issue on a Lenovo laptop powered by i7-1065G7 running Fedora 35.

Over on the Framework community forum, affected users have been raising this issue for close to a week now, and it looks like an Intel Linux kernel engineer, Ville Syrjäl, had picked it up.

He wrote:

After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel.
[..] I recommend immediate revert of this stuff, and new stable release ASAP. Plus a recommendation that no one using laptops with Intel GPUs run 5.19.12.

The 5.19.12 changes have been reverted with a new stable release (5.19.13). Users are reporting that this has indeed fixed the issue.
