stacking actions seems to hang editor

Hi, As mentioned on the forum thread my editor hangs a lot.

Seems to happen when I drag a slider (or other control) that would make a lot of iteratively-stacking operation happen.

Like "increasing the contrast slider" which needs to update 25 terrains and all the requisite logic hanging from that.

When this occurs the computer shows the last icon from the "adjustment" you were trying to make and just never returns.

I have no better details beyond the exact screenshots I shared on the forum page of what I touched. There appears to be no - logical - link beyond "I requested a change" and that change extrapolated out the be a lot of changes from a tiny control. That's when it usually hangs.
