I like to use
undercurl to highlight spelling mistakes in Vim. I believe it does this by default. This works fine in MacOS and Linux but it isn't visible for
gvim on Windows 10. Originally, I thought it was missing but it turns out that it's there very faintly.
I apologize for the bad font but this is what I get when I use
-u NONE. It also doesn't work with my customized font,
Compare this to the same settings on Mac. The
undercurl is more visible.
Is there a way to get
undercurl to display more boldly on Windows 10? I am using
gvim 8.2. I found this question but it's not relevant since I still have the the problem with a minimal configuration (i.e. no
colorscheme. Maybe another font is better? Some accessibility setting?
