Almost see through small glitches on the "bounding" box areas of all blocks, its just easier to see on dark ones such as nether brick, I assume its part of a texture pack glitch from the new format not properly lining up the textures flush to each other.

I'm pretty sure this issue has been around for a long time, I can't recall a time when blocks did not do that. It might be more pronounced in the snapshot.
Hmmm, ive never had this issue, just appeared to me on the snapshot, i really wana mess with hoppers but cant stand this glitch, ill stay on 1.4.6 and wait hopefully it isnt there on 1.5...
EDIT - run around in a nether fortress YUUUUCK! its almost unplayable ugly.
If you have any kind of anisotropic filtering on through graphics card's or Inegrated graphics UIs it will cause these lines to show up or be more pronounced. Make sure no anisotropic filtering is being forced on your Minecraft.
Just went back an checked my 1.4.7, and those lines aren't nearly as noticeable as your screen shots.
