Ok, that was caused by enabling both x11 and wayland in
DISTRO_FEATURES. It was fixed by adding "x11" to
DISTRO_FEATURES_remove

Anyway, I have created build with fsl-community-bsp at daisy. There
are the same issue.
For example, 5 instances of weston-simple-egl-client produces 35FPS
each. I think, that rendering of five rotating triangles should be
faster.

I suspect that it is caused by Vivante's wayland-egl implementation.
But I have no idea what to do with this.
