Green artifact at right side bottom bug appears not
always, it depends from clip content. Aprox. appearance
is by my experiences about 50-60%. Only in YUY2 mode.

    Does this happen with 2.5.6?

    Blur/Sharpen was extensively refactored and bug fixed from
    2.5.5. Particular attention was given to the boundary
    conditions which prior version treated inconsistantly and
    arbitarily.

    According to ppera2 the bug (green line at bottom) is still
    present in beta4.

    I can reproduce something like the problem under 2.5.5, but
    the whole right edge is green rather than just the bottom right
    corner. This fault is caused by the MMX code running past
    the end of the line and bluring in the crap from past the right
    edge. This I have already fixed for 2.5.6.

    To proceed I need a 1 frame raw yuy2 or huffyuv yuy2
    compressed .avi of a frame that causes the problem with an
    AVS script like this.

    AviSource("one_frame.avi")
    Blur(1)
    ConvertToRGB()

    Again I ask, does this happen with 2.5.6 since Blur was
    refactored? I can easily reproduce the problem with 2.5.5 but
    not with any recent 2.5.6.

    Ok, i checked it with ppera2. There's no green line in the
    latest binaries. (I guess he used some older version when
    testing it.)
