patch 8.0.0592: if a job writes to a buffer screen is not updated commit https://github.com/vim/vim/commit/29ae377ea7039874337bc79ace9ab2b37b9056e5 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Apr 30 19:39:39 2017 +0200 patch 8.0.0592: if a job writes to a buffer screen is not updated Problem: If a job writes to a buffer and the user is typing a command, the screen isn't updated. When a message is displayed the changed buffer may cause it to be cleared. (Ramel Eshed) Solution: Update the screen and then the command line if the screen didn't scroll. Avoid inserting screen lines, as it clears any message. Update the status line when the buffer changed.
