[b6] Changing Automation Curve Makes Clipp An Stutter

during playback of a song or pattern, if i modify the automation curve it starts tripping over itself.
i gather these curves are implicitly linked to the pattern editor and the play line.

if this can’t be fixed for 1.8.0 or if this is just a problem on my system,
could automation curve changiing be better handled with a faster mobo/cpu combo?
