Glass texture bug?

[gunzmaster95 0]

I am currently playing on my single player world tfc, and i noticed my glass wall looks very strange. Instead of adjacent glass blocks masking each others hidden faces, some of the faces are showing through the adjacent glass blocks. For example, if you put two glass blocks next to each other, and stand in front of them so the one blocks the other, it SHOULD mask it, however, i still see some of the faces of the glass block. it seems to be very random, and for some reason, i cannot reproduce this in any other worlds. If anyone has any idea why this is happening, please let me know.

Edit: I posted some screenshots.

Not that I think it would matter, but did you use the same color sand to make all the glass? If you're looking for the wall to just be one giant sheet of glass, I suggest using optifine or some other client-side mod/texture pack that adds connected textures.

Well, i believe i did use the same color sand, but it is possible i didnt. However, i tested different sand colors making glass and they seemed to act like normal glass would. As i said, in other worlds i don't have this problem, and i don't want a giant sheet of glass like connected textures from optifine. I just want what a normal glass wall would look like in vanilla minecraft. But for some reason, the glass blocks don't seem to work properly.
