Did you change your graphics mode to fast? Because that could cause aliasing artefacts. BetterNether should otherwise not change the rendering in the overworld.

Ok yes, going up to fancy fixed it. Thanks for the quick help :)
It's weird though, it clearly only happens when better nether (or better end) is activated. Without it everything looks fine even on fast.
