commit https://github.com/vim/vim/commit/da3a77d9ec28407b8fa2aa014e76944d0a525662 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jul 10 23:16:09 2016 +0200 patch 7.4.2025 Problem: The cursor blinking stops or is irregular when receiving date over a channel and writing it in a buffer, and when updating the status line. (Ramel Eshed) Solution: Make it a bit better by flushing GUI output. Don't redraw the cursor after updating the screen if the blink state is off.
