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.</pre>
