LSP hover popup hard to read

[TisnKu]

Thanks for the great theme! The background color of lsp hover is the same with buffer editor:

@TisnKu During the refactoring process, I resolved the issue but forgot to reference it. To ensure the fix is implemented, please use commit 4d5a4ce on the main branch or a later revision.

I just tried and it works.

But for some theme the hover is still not very obvious. So I enabled hover border as a workaround.

Hi. still I could not get the borders shown for the high contrast theme. I use lsp zero nvim package with default recommended preset. I could see the borders for telescope floats but not for lsp floats. Am I missing anything?

It's either the highlights, or floating window config (i.e. it might not even be configured to draw a border). I'm not familiar with lsp zero, but by default in neovim, hover and signature popups/floats use the highlight group FloatBorder for their borders. If that plugin is following the defaults, you can do :verb hi FloatBorder to see the highlight definition and visualize what colors are getting used for the border. By using :verb, it should also tell you where that highlight group was last set.

For example:

After running that command, if the fg color is clearly visible in the highlight example (as it is in my screenshot), then you'll need to refer to the config and docs of lsp zero to ensure that these float borders are properly configured. I believe that telescope uses its own custom highlight groups for its float borders, which may or may not link back to FloatBorder.
