You can see the behaviour on this streamable video. As you can see, I'm just going up and down and text gets redrawn as I do that.
It would be very impractical to call
:redraw function manually every time I use
I tried writing wrapper functions that call
redraw after that, but to no avail. I also tried modifying source code for the
fzf#vim#complete#line function by calling
redraw right after it, but it didn't help either.
