Xwayland under sway invisible running x11 apps.

[Jesper Schmitz Mouridsen]

Hi

The difference was the wayland option in mesa-libs

it was turned off. Turning it back on and the problem is back. So there 
might be a problem with libEGL on ivybridge. Also see 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237662.

Firefox with MOZ_ACCELERATED=1 renders a light gray surface and no 
visible context...
