Graphic Issue (I dont use textmod)

Whenever there is a portal in eotn, fires or waterfalls, something that has a squiggle animation, i see it no matter where i am
For example if im in a dungeon, i see random movements in walls if there is a fire behind it, or behind a wall behind that wall

I mean this hasnt always happened, i think it happened after an update in my gfx card (Ati radeon x1800 series)
I mean its not a serious issue but it does get annoying after a while

Anyone know how to fix it?
WOuld be greatly appreciated

Mod edit: Please post smaller images. Thanks!

Sounds like a corrupted gw.dat perhaps. Over time it may correct itself or you could try using -repair or -image.

How would i do that?

Re-install your gw.dat file. I had a similar problem with bubbles over every fire. It fixed it

done all that, new dat file, still the same problem
Im thinking its a problem with the graphics card itself
