titlestring causes flicking in nvim/tmux on large screens with splits

[HunterWare]

The current title string causes issues with large screens in tmux/nvim. The constant updating of the title will cause occasional flickers and since it is changing on cursor movement it causes a lot of cursor flickering.

Changing from:
set title titlestring=%{progname}\ %f\ +%l\ #%{TmuxNavigateDirections()}
to:
set title titlestring=%{progname}\ #%{TmuxNavigateDirections()}
will effectively hide the issue.

Admittedly this doesn't happen in vim with Tmux. But with Neovim in a large (wide screen monitor 500x100) terminal with side by side Tmux splits it gets pretty unusable. I might suggest that the plugin only set the minimum titlestring it needs, and one could have extra stuff with a tmux-navigate-mid-titlestring that might default to "%f\ +%l\ ". Then the user could remove the extra stuff by just clearing that variable?

This would allow a non-forking work-around to: neovim/neovim#13095

Thanks for your report. 👍 Could you please check whether the issue occurs if %f is kept and only %l is omitted? 🤔

I think that the issue is really a neovim problem with the redraw, but when you change the title with every line change that adds up. =) I didn’t see the issue with %f.

Great! 👌 I have removed %l from the titlestring in commit 52da3cd. Cheers.
