Terminal flickering when scrolloff is not zero

[quebin31]

I was getting some flickering when using Nuake, I think it was because scrolloff was set to 5. Setting it locally to zero fix flickering if global scrolloff is not zero.

The problem with scrolloff is that it can't be set locally. If we add this to s:InitWindow(), after toggling Nuake, it will override the global value.

Ohhh, but it's actually a problem when scrolloff isn't zero when you hit Ctrl+L to clean the terminal and start writing again it goes crazy, what can be done?

Edit: Maybe we can set scrolloff to zero while Nuake is active, then restore it's value when inactive.

Firstly let's investigate the problem because, to be honest, I can use Ctrl+L without a problem ;)

Which version of vim/neovim do you use?

I have scrolloff set to 5. I've tested it with zsh and bash and it starts to "flicker"
