Vertical lines issue

[xbladesub]

I'm not sure is it line height or something else, but with JetBrains mono font I have this kind of empty spaces.
Everything is ok in Iterm2 for example. What is the problem and is it possible to fix that?

Any updates on this? I'd love to increase the line height but have the actual vertical lines render properly here.

• And as mentioned in this one I think that we should have a fallback font for certain characters, that always fills the whole height and width Customizing line height #481

I am also interested in this. The issue is reproduced with almost any font when linespace is set to be bigger than zero.
Is it solvable by adding specific (which-one?) fond fallback in user config, or it should be solved by neovide internally?
