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.

Comment 2 Matthieu Gautier 2015-09-25 14:56:08 UTC 
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
[drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun
Comment 3 Fedora End Of Life 2016-07-19 17:39:24 UTC 
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
