Unity5 Android mip-mapping problem

Hi,

i'm creating a game that will be on android but ran into a problem with my terrain and textures in general.

When mip-mapping is enabled on textures i get weird colored lines and artifacts (depicted in the picture below) now i didn't had this problem with unity 4.6 but since the convertion to v5 it showed up on the device. The device uses the TEGRA 3 SoC.

Is there a solution to this problem or did something change in unity5 that i'm still not yet aware of ?

It's those green and black matrix alike lines in the background mip-map 0 area doesn't have it.

Thanks
