I’ve tested on several iOS devices and several different games. On all of them grass looks horrible.
It looks like you’re experiencing a lot of lag in that picture. That could be why?
Same for Android, lag or not it’s bad material.
Still an issue
Looks like the grass texture gets patterny at a distance to save on memory, sort of like the grass texture on xbox minecraft. Except too much.
Tried it on my Android phone yesterday and was actually going to post a bug report about it now… until I saw this!
@berezaa - You may want to edit the title as it doesn’t just happen on iOS
