The regular flash plugin 10.2 doesn't have vaapi (Intel) support

The Chrome flash plugin (10.7?) doesn't have any vaapi or vdpau support

You best option is to install the vdpau to vaapi wrapper and disable the
Chrome flash plugin https://github.com/i-rinat/libvdpau-va-gl

This will revert you back to the older 10.2 flash version which should work

I think I also had to override a few settings in the flash dot file to get
it to skip GPU validation along with following the instruction for the
above project

Its quite convoluted but least it makes YouTube work

It is indeed F19.

Easy test: go to youtube, and watch things that are in 1080p HD. They
play fine in a window (using about 70% CPU), but full-screened to
2560x1440 they play at about one or two frames per second.

Non-HD content seems to be fine even full-screen. Either just because
it's so much easier to do, or because some level of scaling is

It may well be that I'm using chrome (and chrome seems to tend to use
its own library versions), and firefox indeed seems to be a bit
better. But by "a bit better" I mean closer to full frame rate in
full-screen, but lots of tearing - and it was stil using 70% CPU when
displaying in a window. So I think firefox is also still doing
everything in software but may be better about using threads for it.

My previous i5-670 which was inferior in almost every other way didn't
have these problems.. It had the same 2560x1440 display.
