For example, I use
set cursorline and move to the next time, the remnant of the cursorline remains. Same goes to when I type
:, the bottom panel is supposed to be cleared, but the text remained there, which is really annoying. I also tried
vim -U NONE -u NONE -N but it didn't solve the problem either. My system is xterm and vim is able to detect the right xterm. I am at a loss as to how to fixed the problem.
I did find a temporary solution, that is type
:!clear in Vim, which will keep Vim functional for the session, but it's annoying that I have do this every time I go to vim. Just wondering if there is a better solution.
