Problim with textures on terrain

I see a clear boundary between the different levels of mipmaps in textures on the terrain. (I think this is a boundary between mipmap levels) The problem is very annoying, especially in movement. It is solved by the turning on anisotropic filtering, but anisotropic filtering very heavily loads weak mobile devices and is not supported by everyone. Are there any reasonable ways to solve the problem besides anisotropic filtering?

Enabling trilinear filtering on your textures will blend over the mip borders rather than abruptly switching, but yeah the only real solution for this is anisotropic filtering.
