Only way seems to be running the game in DX9 instead of DX10.

For me running it in DX9 is unacceptable though since my fps suffer quite a bit doing so.

maybe if you change to 24 bit?

That's not the solution for sure, but thanks for the suggestion :)

I experimented for days trying to sort it out. Only solution that works is setting the renderer in conf.ini to either DX9 or DX11, both of which either degrade fps or visual quality quite a bit.

I'm happy with direct x 10 giving the current state of the game, 3 blue lines on the horizon is harmless compared to the big picture
