Steps to reproduce

Setup keybindings to change focus. For example

    , {"command": "moveFocusLeft", "keys": ["alt+h"]}
    , {"command": "moveFocusRight", "keys": ["alt+l"]}
    , {"command": "moveFocusUp", "keys": ["alt+k"]}
    , {"command": "moveFocusDown", "keys": ["alt+j"]}

Expected behavior

As soon as I change focus to another pane the cursor should immediately appear in the newly focused pane.

Actual behavior

There is a delay.

If I change focus quickly multiple times using the keybinding it is hard for the eye to track where to focus because the cursor does not ever appear until you stop pressing the focus change key.

There is also the pane border color change on focus but for some reason the color contrast there is difficult for me to track. I prefer to look for the cursor.

What I think is happening is that when you change focus to a new pane the cursor blink state machine starts again from zero and zero is the off state.

A fix might be to have the zero state of the cursor to be on rather than off.

With the mouse

The same problem happens when focusing the pane with the mouse. There is a delay.

Other Applications

I've noticed that the old power shell console and cmd.exe console seem to have the same probem.

gvim seems to get it right. Switching text editing panes quickly shows the cursor immediately.
