There really is nothing I can do to fix it ... the original thread regarding it way back in 4.1 is here...

I've been looking at the code for it for the last hour, aswell as looking online to see if anyone found a solution since I know there are other addons that do the glow..
The textures are cached in memory the way they should be, and there is nothing else to the code except 2 calls, one SetBlipTexture(texture1) and one SetBlipTexture(texture2)
I tried even removing the 1 texture, and just having it call the bright one over and over and it still flickers.
It's either I remove it completely (which I tried doing before and people wanted it back) or we continue to live with setting glow to 0 if your not farming.
