After updating to xorg-x11-server-1.19.0-0.1.20160929.fc25 and
xorg-x11-drv-nouveau-1.0.13-1.fc25 (from
<https://bodhi.fedoraproject.org/updates/FEDORA-2016-a5c3ebe67a>) video
playback in totem stutters every few seconds to the point of being unwatchable.
It doesn't happen with video playback (e.g. YouTube) in Firefox, and system
generally works fine. Downgrading the update "fixes" the problem.


I'm using X11 with nouveau on a GT216M (GeForce GT 240M), no hybrid cards:

Hans de Goede in <https://bugzilla.redhat.com/show_bug.cgi?id=1381014> kindly
helped to discover that xf86-video-nouveau-1.0.13 does not show this problem
with xserver-1.18.4, but does show it with xserver-1.19-rc1, and that using the
modesetting driver with xserver-1.19-rc1 makes the problem go away.
