How to remove the bottom blank line under vim full screen?

  question, vim


The purple part at the bottom has a border and a little bit.

It is impossible to remove the bottom margin under ubuntu. Let me tell you why:
The essential reason is that the line height displayed by the characters below terminal is fixed … when the terminal window is maximized, the form height is often not an integer multiple of the line height …
I have the same problem as you, but I do have a folk prescription … that is to adjust the terminal font size … to make the height of the form close to an integer multiple of the line height …
