The neovim main text buffer window gets blank after deleting more lines with VISUAL LINE.
Interesting note: after saving with :w and refreshing with e!, the selected deleted lines are correct, so the text data is still there and it seems just like a rendering problem.
Steps to reproduce:
Select 3 or more entire lines in VISUAL LINE mode with V and then press d to delete them. The main text buffer should turn blank after.
