If you want to keep the background in "software" then select filtering to 3,if you want it to be filtered(but some glitches will appear)set it to 2.
If you choose 2 and that you have a nvidia card then go to the D3D control panel then press advanced and pull the slide bar on 7(it changes the texel alignement).
Also,if your card support FSAA try enabling it,the glitches will almost disapear.
