TUI: Terminal cursor blinks after exiting neovim

[RobbieClarken]

Neovim version (nvim -v)

NVIM v0.9.0-dev-590+g6ba34e21f

Vim (not Nvim) behaves the same?

no

Operating system/version

macOS 12.5.1

Terminal name/version

iTerm2 3.4.12

$TERM environment variable

xterm-256color

Installation

build from repo

How to reproduce the issue

1. Have terminal cursor configured to be a solid block (this is the default in macOS Terminal):

   

2. Install latest neovim from master branch.

3. Open and close vim:

   nvim --clean
   :q
   

The terminal cursor will now be blinking whereas it should be solid:

nvim-blink.mp4

A git bisect indicates this bug was introduced in one of these two commits:

• 2448816
• 43e8ec9

I was unable to compile 2448816.

I can replicate this in iTerm2 3.4.12 and Terminal 2.12.7.

Expected behavior

The terminal cursor should remain the solid (not blinking) block.

Actual behavior

The terminal cursor changed to be blinking.

I want to add one point: I use au VimLeave * set guicursor=a:ver1 to restore to vertical bar cursor style after leaving neovim, but now after exiting neovim the cursor is blinking block. My terminal is konsole 22.08.3.

I tested #21625 and it seems to make the behavior the same as v0.8.2 in Konsole. Can anyone check if #21625 fixes the problem for iTerm2?

Was facing this same problem and this does seem to fix the problem. My test is with the foot terminal on Arch Linux.

I can confirm #21625 fixes the problem for iTerm2 and Terminal on mac.

It's almost the same, though possibly more correct.

My terminal cursor is a blinking underline and I was using this to restore it on exit:

au VimLeave * set guicursor=a:hor25

It broke with #18375 and #21625 fixes it, but I had to change that to get the blinking back:

au VimLeave * set guicursor=a:hor25-blinkon500

I can confirm that #21625 fixes the issue for me with Terminator on Arch Linux.
