Looks like a bug. If you haven't raised up a ticket yourself, I think support will do it for you and will help you out for sure.
It means 16bit fades on an 8bit dimmer, adjacent channels/dimmers were pulsing to the rise and fall in the fine value, spectacular but not wanted.
Great support from Matthew in Melbourne, headed us toward the last 8 bit fade version, which has some janky hiccups on the inability to fade in a program with an oscillator in play.
Maybe there's a need to create a patch where the choice of dimmer / intensity is 16 or 8 bit?.
Andrew, not sure what you mean. Is there a way you can share a video with it?
In this case it is worth making Fade programs in EMU (see attached video) and then trigger EMU programs using MIDI notes in Ableton. As the result you'll get automation you want, if I understood right.
