Hi! glxgears running at exactly under 60fps means vsync is enabled. I 
mean, it literally tells you: "Running synchronized to the vertical 
refresh. The framerate should be approximately the same as the monitor 
refresh rate."

You can run 'vblank_mode=0 glxgears' on the old mesa to see its 
performance without vsync.

In Firefox, open about:support and scroll to the Graphics section.
If "WebGL 1 Driver Renderer" mentions the name of your GPU (e.g.: X.Org 
-- AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.19.0 / 
12.0-CURRENT, LLVM 5.0.1)), that's good. If it mentions 'llvmpipe', 
that's bad.

I'm pretty sure you are actually running swrast, because it does not 
vsync in glxgears by default, while GPU drivers do. And of course, 
"failed to load driver: i965" and "AIGLX: reverting to software rendering".

The most helpful message is "Kernel 3.9 required"…

When was Haswell support merged into stable? 11.2? if so, <=11.1 would 
need to stay on Mesa <18.0.
