Tearing with opengl-hq and not with opengl on Gnome with MPV

Hello, I'm on Fedora 23 with Linux 4.4, Gnome Shell 3.18, MPV 0.17 and Nouveau
driver (Nvidia GT430). In windowed mode I have tearing with opengl-hq and not
with opengl. In fullscreen mode there is no tearing with both opengl-hq and
opengl.

Here is the commands to test

mpv --no-config --vo=opengl-hq movie.mkv
mpv --no-config --vo=opengl movie.mkv

With Netrunner 14.2 (KDE - Kubuntu 14.04 derivative), MPV 0.17 and Nvidia
proprietary drivers there is no tearing in windowed mode with opengl-hq. I
tried Gnome Shell and Plasma 5 on Manjaro too. There is no tearing with Nouveau
and Opengl-hq in windowed mode in Plasma 5 but there is stutter and there is
tearing with Gnome Shell.

Actually there is dropped frames with Nouveau and Opengl-hq in windowed mode in
all DE.

I opened an issue on MPV github and Wm4, the main MPV dev, said that my GPU
(Nvidia GT430) with Nouveau driver is maybe too slow (no reclocking ?).

For me the logical behavior should be like on Plasma 5 with Nouveau, no tearing
but if the GPU is not powerful enough the playback have stutter due to the
dropped frames.

I contacted Rui Matos, a Mutter developper, and he advise me to file a bug
here. Here is a summary of our talk to give all the infos I have :

Rui : Did you try gnome-shell on this environment (same as Plasma 5)? I
supposed it'd still tear.

Me : I tried Plasma 5 and Gnome Shell on Manjaro with Nouveau on the same
installation. The tearing was present in Gnome Shell but not on Plasma 5.

Rui : I'm afraid I can't help with this one, you'll have to file a nouveau bug.

Me: Can you confirm that even if the tearing was present in Gnome Shell but not
on Plasma 5 on the same install I should file a bug to Nouveau.

Rui: Is kwin using opengl compositing? For the comparison to be meaningful you
need to compare gnome-shell with kwin with opengl compositing enabled.

Me: I just checked to be sure and the opengl compositing is enabled for kwin
too.

Rui: Ok. I still might be a driver issue that just happens to be triggered by
different timings and API usage in mutter vs. kwin. Anyway, I can't really do
much without the hardware to test, so it's still better to report it to
nouveau.
