Ubuntu 64 14.04, Nvidia GTX 460
Broken: official 2.71 and built e85bcfa (18-08-2014)
Short description of error
While trying to have a freestyle layer, and a normal one, I've found that if you disable 'Use surfaces' in the first renderlayer, it affects the second layer.
Exact steps for others to reproduce the error
Just render. The second layer should render fine, and it doesnt. If you disable the first renderlayer, the second one renders fine.
