Slow Video Failure

System Environment
=======
OS: Linux Ubuntu 17.04 64 bits
Kernel: 4.12.0-rc3-drm-tip-ww2-commit-187376e+
X-Org: 1.19.99.1

Regression?
=======
No

Bug detailed description
=======
Videos have frame rate issues as they seem to get stuck momentarily (specially with the FLV/SWF formats), the higher the resolution, the heavier the problem

Reproduce Steps
==============
Open a video (streamed or local), from 720p resolution and up

Expected Result
=============
It should play at normal speed.

Actual Result
===========
Plays intermittently at different frame rates with a regular frame drop.

Analysis & Root Cause
===================
Possible and maybe required bottleneck detection within the graphics stack (even per-output port display sequencing), improper buffer usage.

Bug is invalid, this behavior and more can be found at a more generic-level bug
