also I hit another issue ;-)

- running report on data with callchains, and the screen is populated to the middle
- press 'END' key and the cursor goes to the bottom of the screen (I can tell based
  on the scrollbar), but there are no entries

I could make the cursor appear by pressing UP arrow, I bisected to:
  f214833 perf report: Add --percentage option

not sure where's the problem

thanks,
jirka
