Can't have transparent background Everywhere about sonokai HOT 3 CLOSED

Thank you for your answer and tips 🙂. I understand a little better how the Vim UI works.

Indeed, I use Windows Terminal which supports blurred background and that's why, for better appearance, I disabled as many backgrounds as possible using:

let g:sonokai_transparent_background=2

Also, what I like about the transparency of Vim is that it is pseudo-transparent actually, inside the Vim UI and you can't see through a floating window even if it's "transparent".
Floating transparent windows actually just takes the lowest background of the UI at that specific area.
With borders it's even better like here:

Even if there is text behind the floating window, the text will not appear and will be covered by pseudo-transparent background.
Unless I misunderstood something.

This is precisely want I need to achieve for all my floating windows.

Should look at how to customize the background for each plugin that uses floating windows or is there a way to overwrite the default appearance of all floating windows of Vim?

Thanks in advance for your time 🙂.

Edit : I finally found that I just had to define the following highlight commands:

vim.cmd("hi NormalFloat ctermbg=NONE guibg=NONE")
vim.cmd("hi FloatTitle ctermbg=NONE guibg=NONE")
vim.cmd("hi FloatBorder ctermbg=NONE guibg=NONE")

And here is the result for Mason.nvim for example :

Went from :

to:

Should add this for LSP Diagnostics

vim.cmd("hi DiagnosticFloatingHint  ctermbg=NONE guibg=NONE guifg=#42E66C")
vim.cmd("hi DiagnosticFloatingInfo ctermbg=NONE guibg=NONE guifg=#0876c5")
vim.cmd("hi DiagnosticFloatingWarn ctermbg=NONE guibg=NONE guifg=#E8AB53")
vim.cmd("hi DiagnosticFloatingError ctermbg=NONE guibg=NONE guifg=#ff5189")

Freely choosing foreground colors (guifg)

output:

Thank you for your attention.

I thought setting NormalFloat (which is the default highlight group of floating window) to be transparent, but the problem is that not all floating window have a border, instead the designs in most of them are using a brighter background to distinguish between normal background colors, so I gave up this idea.

Another thing that needs to be considered is that vim actually shouldn't make everything transparent, some elements should use a different background color (e.g. the status line). If you want to make your vim fully transparent, you should consider switching to a terminal emulator that supports blurred background (e.g. konsole). This will fully blur every elements in vim, which will look much better.

Any solutions for Linux? I have the same problem on Arch Linux with Alacritty. The solution above didn't help.
