[Bug 97056] Screen flickering problems on Acer laptops from 4.6 kernel

--- Comment #4 from Olivier Cortès <olive at deep-ocean.net> ---
I've got same symtoms on Lenovo Yoga2 pro (hidpi), under Arch linux, stock
kernel 4.6.4-1-ARCH. xf86-video-intel version 1:2.99.917+688+g49daf5d-1 (stock
arch package, updated daily).

Sorry for the delay ; the problem has been happening for at least 2 months, but
it took me ages to qualify it, and find it here on this bugtracker.

Flickering happens every now and then (between one minute and 1-2 hour after
having opened my graphical session).

I can barely stop it by moving a lot my mouse cursor (screen stops flickering
until i stop moving the cursor, where flickering happens again immediately).

Flickering is resolved more durably by suspending the machine: on resume, I can
work again until next flickering sequence (idem, between 1 minute and some
hours).

I'm currently testing the "i915.enable_psr=0" workaround to see if the bug
occurs again. I will report here.

Feel free to ask me about any missing information.
