When you use a high res texturepack seeds displayed in the seed storage are displayed smaller. You can also see other neiboured textures on the Texturemap

Im using FTB Infinity Evolved (2.2.2) With Agricraft 1.4.5

I should have fixed that, check out version 1.4.6-pre2, it should be fixed in that one.

Closing due to no response and I believe it has been fixed.
