graphical glitches video

Description of problem:
Graphical glitches appear randomly.

It's seems as if an old version of the screen is used instead of the right current one.

Everything else (pointer/keyboard input) work as if there were no glitches.

Atl-tab to change focused windows fix the actual glitches (but doesn't prevent news to come)

see attached video.

Version-Release number of selected component (if applicable):
Fedora 22

How reproducible:
Glitches appear frequently but I've no exact "always reproducer"
On the video, loading a stackoverflow page seems to reproduce the bug
but not all the time and I can have the bug without it.

Expected results:
No glitches

Additional info:
I'm using a MacBook Pro with a intel and a AMD video cards.
I deactivate the AMD card and use the intel one using this modification to grub : https://bugzilla.redhat.com/show_bug.cgi?id=765954#c62

First appearance of the bug I recall is from 31 July 2015. No problem before.
Using gnome-shell wayland, no glitch.

dmesg contains several times those messages and it seems to correspond to when the glitches appear:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
[drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
