commit https://github.com/vim/vim/commit/107abd2ca53c31fd3bb40d77ff296e98eaae2975 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Aug 12 14:08:25 2016 +0200 patch 7.4.2199 Problem: In the GUI the cursor is hidden when redrawing any window, causing flicker. Solution: Only undraw the cursor when updating the window it's in.
