(tfx.fx, 380ish line, uv = st.xyxy + HalfTexel

For that static thing, doing HalfTexel * 4095.0 / 4096.0 was enough. But I would still get this lines on foliage and even character sprites for example. For that to finally disappear, I had to go down to HalfTexel * 4080.0 / 4096.0.

Worth to take a look perhaps? I dunno if anyone else have the same problem though.

#EDIT: Better one.

Code:

(GSRendererDX.cpp, line 304)
ps_cb.HalfTexel = GSVector4(-0.5f + 1.0f/WH.x, 0.5f -1.0f/WH.y).xxyy() / WH.zwzw();
