Filter is only applied if both X and Y are scaled to more than double. (As a side note, I'm not sure exactly why it has to result in blurring - is this a bug, using wrong coefficients or something like that, or unavoidable?)

I added this since I noticed this comment in radeon_textured_video.c: * Applying the bicubic filter with a scale of less than 200% * results in a blurred picture, so disable the filter. Anyway I am against applying such filter by default since they loose details of the video (I usually prefer to see the original encoded video without filters) and can also overlaps with filters used by video players. However I am not sure why it's enabled when scaled larger than 2x, but not otherwise.
