            Bug ID: 116431
           Summary: Screen Flickering On Intel
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.5.0
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - Intel)
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: carlo.abelli at gmail.com

        Regression: No

I have a Dell XPS 13 running Arch Linux. Updating to kernel version 4.5.0 has
caused screen flickering (quick black flashes that come in bursts). Downgrading
to 4.4.5 does fix this flickering. Not sure exactly what the issue is but it
persists whether the xf86-video-intel driver is installed or not.

dmesg reports the following error when running kernel 4.5.0 but not 4.4.5:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun

Perhaps this is related. Here the thread on Arch Linux forums:
