The Linux graphics stack has switched to libglvnd while the FreeBSD
stack has not so I don't know if Linux libglvnd can figure which stack,
mesa or nvidia, it has to load.  Try deleting
/compat/linux/usr/lib/libGLX_system.so.0 or making it a symlink to
/compat/linux/usr/lib/libGLX_nvidia.so.0 or try deleting linux-c7-dri
package.
