Tenchu: Wrath of Heaven, lines in the sky

[gamer4eternity]

Hi guys, Im currently playing Tenchu: Wrath of Heaven and everything works fine besides that there are some weird lines in the skybox.
I checked gameplay videos of other people playing in pcsx2 and they dont seem to have this problem.
Theres always at least one of those lines in the sky, sometimes more visible and sometimes less.

Anyone know how to fix?
Anyone know settings that are likely to fix this kind of graphical glitch/bug?

Hope someone can help.

tried half pixel offset ?

Sadly this did not work, normal (vertex) even caused more lines to appear when moving the camera angle.

Thanks for the help.
