Calling SendViaOSC52 Causes Terminal to Flicker

[AnastasiusVivaldus]

Thanks for this awesome plugin! After trying X11-forwarding, and other attempts at OSC52, this is the first that seems to really work well across different platforms.

The only question I have concerns the way it causes my terminal to flicker. I had hoped to include it in every yank, but that's not viable because it causes a big flicker each time. Not a massive deal, but if there's an easy fix then that would be appreciated.

Thanks! Try setting lazyredraw in vim and see if it helps. If does not, it might just be terminal-dependent.

Hello,

I have just pushed a commit that should prevent the flicker; let me know if it works for you too, and I'll close the issue.

I tried it just now ssh-ing into an AWS microVM (Ubuntu 18) with Vim 8.2 in iTerm2 and, unfortunately, it causes my screen to blank. Here is a screen recording of me doing a simple yank on the relevant lines in my .vimrc

Let me know if there's any debug info I might send to help figure out what's happening here.

Edit: Note: I also tried it just now on my MacBookPro and got the same behavior.

Pushed another commit that adds two options:

• g:osc52_print: can be 'echo' (default), 'printf' or a vim expression to which the osc52 sequence will be appended;
• g:osc52_redraw: can be 2 (default: erase and redraw, causes flicker), 1 (redraw without erasing) or 0 (no redraw).

Try tinkering with both options. On my side, I use g:osc52_print = 'print' and g:osc52_redraw = 0, on minTTY and tmux, without issue nor flicker. It is probably very much terminal-dependent.
