LMMS (Linux MultiMedia Studio)

I've seen this behaviour in Win build (under Win'2000) and in Linux build
under Kubuntu 8 as well. I can't meditate properly to formulate the most
formal description, thus just an example: if you load a 303 VCF into effect
slot then create TWO automation tracks, link 303VCF's left channel cutoff
to the first auto track and the right channel cutoff to the second auto
track, then you get both channels' cutoffs change equally and
simultaneously.
An mmpz is attached, where the situation is exactly as described. Even
though 'Link channels' is turned off in 303VCF, the two knobs rotate
simultaneously, disregarding the two auto tracks differ completely.
Or, perhaps, not, as they seem to jitter while moving - maybe, that's the
second auto track tries to speak?
