[stable] OpenGL problem:bay trail

[dE <de.techno@gmail.com>]

Hi.

I've a bay trail processor with HD graphics.

I've enabled hardware Firefox hardware acceleration (downloaded from 
Mozilla) but it's extremely slow; not at par to this graphics chip.

Even the GTK UI and scrolling is slow at 1024x768 resolution.

I thought this was an upstream problem, but it works fine with Fedora 20 
which uses 3.15 kernel.

I'm using backproted 3.16 kernel.

Any suggestions/hints?
