Is there any update for this issue, please?

It looks like nvim doesn't clear the screen, but draws on top, while Vim clears the screen.
That causes some flicker, but it makes sure that there are no remaining drawing artifacts (from the resizing, shell commands, etc.). Also, Vim is optimized to minimize output to the terminal.

Thank you for the explanation. I don't know much about how vim handles this problem but as a normal user, I think vim should change the way it works with screen clearing because it makes the user experience less comfortable more in long run.

There are some quite similar issues with how vim handle clearing screen #8002 #8002

Anyway, it's just my opinion. Perhaps other users have a different or similar opinion to mine.
