Antialiasing error when publishing

I posted this before and thought it had to do with the fact that i’m using deferred and had AA turned on in the quality settings. I dont. I’m using FXAA1 Preset A. I get this error every time I publish. What causes this and how can I fix it? Thanks.

Have you tried adding that #pragma target 3.0 line? I believe I’ve had the same issue and doing that fixed it for me.
