This sounds very similar to #10754 but I don't think I've seen this for tmux before.

I remember that I didn't have this problem when I used Windows Terminal some time ago. Recently I found that it had this problem.

@huenrong Windows Terminal didn't support the escape sequence for changing the cursor blinking state prior to version 1.9, so that's why you may not have had this problem in the past.

As a temporary solution, you can probably work around the issue by setting TERM=vte-256color before starting tmux, although that may have other unwanted side effects.

In the longer term, Windows Terminal could add an option to block applications from messing with the cursor blinking state, which was one of the ideas suggested in #10754.

Thanks, after setting TERM, it is okay
