Can't scroll in linux repo

[iveqy]

So the linux repo is pretty huge. tig is really slow here, but grv is starting quicker (the second time it's started). Anyway, scrolling in the linux commits makes grv to display some errors:

Thanks for reporting this, and for the demo as well. I haven't tried GRV on the linux repo yet but it looks like it would be a good stress test.

I have a similar issue. I'm using Ubuntu 16.04.
Scrolling Commit or Diff window up to top (causing scroll) after scrolling down to bottom (causing scroll) does not display properly - some lines are not redrawn - only a few lines near the top of the window update.
Interestingly if I do this slowly, like one line at a time (not holding down arrow buttons) then it seems so far to display correctly.
xterm, xterm-256color, screen-256color terminals all show same issue.
But vt100 works ok. (of course no color, etc. so not really a solution - but perhaps it helps with terminfo/ncurses debugging ??)
ok - outside of tmux it works fine with xterm-256color - so I suppose this is looking more like a tmux/ncurses interaction (if my issue is same as here)

ok - final update - if I set term to screen-256color and restart tmux - then it works ok :-)
(I was previously using xterm-256color with tmux)

This should be resolved on master. Please see #39 for more details.
