Pasting text have issues

[hhuangpen]

I am new to neovim, and when I use this plugin, I am having a confusing moment. That is when I paste text (long text like more than couple words) in the input box, it somehow will random delete some text. Let me give you example:

The text try to paste:
This shows the primary selection (Linux/X11 only, usually text you last highlighted).

The text actually paste:
This shows the primary sel1 only, usually ghlighted).
This shows the primary selection (Linux/X1text you last highlighted).
This shows the primary selection (Linux/X11 only, usually ghlighted).
the primary sel1 only, usually ghlighted).
This shows the primary selection (Linux/X1ghlighted).

I tried it different time, it seems random to me how the pasting works.
Note: every other place in neovim pasting seems working fine, even terminal mode.
