Minecraft GUI Flickering (Fixed!)

[Teraku]

I can't for the life of me find a fix for this, so I thought I'd post this here.

Item numbers in my inventory, as well as my XP Level, keep flickering blue/yellow. This I can live with, but this also happens to the huge Mana bar when I'm using Ars Magica, which is very distracting.

I'm using an AMD HD 6970 with the latest drivers, also tried the Beta drivers. Using the LWJGL beta builds didn't help, either.

This is fixed in Minecraft 1.6, but I need a fix for 1.5.2 for obvious reasons.

If anyone has a fix, it would be greatly appreciated.

EDIT: Never mind, fixed it. Downloaded the latest ATI Beta drivers, which stopped items from flickering. The mana bar from Ars Magica flickering was actually caused by the Armor Bar mod included in Hexxit. bspkrs offers a suitable, non-glitchy replacement.
