How can I make fences show up?

This glitch is not because of lighting and fogs problem, it's similar to the dark areas glitch. So the only solution i found is placing a block near the fence, and the fence show up, !IMPORTANT! only if you place the block from west or south to the fence it will work so you probably tried the wrong direction try all four and it will work! like that:

before: after: BUT if you remove the block the fence become invisible again. so just place one block near each row are invisible fence.

According to Notch, this glitch will be fixed in 1.6:

• Fixed fences and stairs sometimes becoming invisible

I know this is an old question, but I fixed this issue by breaking up my very long fence (along a road between two very distant houses; don't know how far in terms of blocks/meters, but it was about 1/2 to 2/3 of a day to walk between them) into shorter sections by putting a stone block in, which also conveniently gave me an attractive place to put a torch to light my way and make my road somewhat safe to travel even at night.

So instead of

FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF [ad nauseum]

I had

FFFFFFFFSFFFFFFFFSFFFFFFFFSFFFFFFFF [etc]

(F = Fence; S = Stone)

Sorry for the lack of a screenshot, but that world has long since been lost. :-(
