I've had this problem for a few days, I see colored lines between all blocks. All settings in the AMD Catalyst Control Center are set to "Use Application Settings" yet I still get this problem. It happens with any texture pack, from default all the way up to 256x Photo Realism.
Hm... Yeah my friend had a problem with this. I asked him about this, and he said that you need to turn off anti aliasing in the video cards control panel or something like that. I hope this helps.
Yes, but see I've tried this. When I turn AA/AF on, I get the very visible lines/grid that many others complain about. but when I change it back to off, i just get those odd dots and lines.
Look in between blocks, they are there.

Any help is appreciated.

I tried it with terrible results. I gave my wife my glasses for a second, a creeper showed up and now my wife is pregnant.
Stupid 3D..
Also I have some Screenshots:
