Yes this is "normal".
You have chosen that particular type field texture - Ozmys Field pack:
http://forums.qhimm.com/index.php?topic=12260.0 - unfortunately imageshack sucks, so you'll have to click on the now-disabled images and hit download to compare.
I promise you'll get used to it; I remember feeling very odd using the pack once upon a time.
To expand on this, you have two options if you hit Configure for "Field Textures - Part 1": Omzy and yarLson.
As described in 7H: "Omzy = fractalized detail, yarLson = preserved detail"
Decide which you prefer, if any.
