[7660:3468:1205/230944.265:ERROR:gles2_cmd_decoder_passthrough_doers.cc(4340)] : NOT IMPLEMENTED

In the past few months worth of dev builds, planned obsolescence has taken effect and Youtube is dropping frames like crazy.  This is a Haswell system -- it should be more than capable.

The latest Firefox plays 60fps 1080p video without dropping any frames.

Notice I disabled all acceleration and all the fancy new features, and it's still dropping frames.

Please don't tell me to enable acceleration - I've done so.

This is a terrible performance regression in the Chromium code.
