System is a ThinkPad T520 (Sandy Bridge running 11.1-Stable  r331492).
The results confuse me a bit as glxgears is clearly running much faster,
but gets errors with mesa-18.

Let me know if I can provide any further information.

mesa-17.3:
> glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
300 frames in 5.0 seconds = 59.883 FPS
299 frames in 5.0 seconds = 59.687 FPS
299 frames in 5.0 seconds = 59.694 FPS

> eglgears_x11 --help
EGL_VERSION = 1.4 (DRI2)

mpv appears to run with functional vaapi. Almost no CPU on a 1920x1080 AVC
file.

I set layers.acceleration.force-enabled to true with no obvious problems,
but I don't know just what to look for.

No errors in Xorg.log

mesa-18
> glxgears
[intel_init_bufmgr: 1788] Kernel 3.9 required.
libGL error: failed to create dri screen
libGL error: failed to load driver: i965
5860 frames in 5.0 seconds = 1171.865 FPS
6060 frames in 5.0 seconds = 1211.919 FPS
5994 frames in 5.0 seconds = 1198.623 FPS
5701 frames in 5.0 seconds = 1140.189 FPS
No idea wht the significance of the errors is.
