Sorry it was like I was talking to myself ^^

I've already encountered this problem while coding PCF, the problem was located in

float2 fracs = frac(shadowTexCoord.xy * ShadowMapSize);

I remember that the solution was something like:

float2 fracs = frac(shadowTexCoord.xy * ShadowMapSize + float2(0.5, 0.5));

EDIT : or it could be something similar when you compute your offsets in:

float2 offset = float2(x, y) * (1.0f / ShadowMapSize);

Try:

float2 offset = (float2(x, y) + float2(0.5, 0.5)) * (1.0f / ShadowMapSize);
