[ESS] How to tame a jumpy iESS buffer?

[John Haman]

Okay, time for another update on this issue. 

I found another possible culprit: the smooth-scrolling package. I had it enabled for ages, and it enforces a margin near the top and bottom of the buffer.

Disabling the package seems to help with jumpiness.

Cheers,
John
