Undercurl color issue

[steakhutzeee]

1. Graphical issue inside a terminal pane (eg. something does not look as it should)

Basic information

zellij --version: 0.40.1

stty size: 55 213

uname -av or ver(Windows): Linux hostname 5.15.146.1-microsoft-standard-WSL2 #1 SMP Thu Jan 11 04:09:03 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Issue description

Using Windows Terminal.

Inside and outside Zellij I do not see undercurls in Neovim.

Applying tmux-256color or wezterm terminfo I'm able to see the following:

Outside of Zellij:

Inside of Zellij:

Any idea on what is causing the colors to change inside Zellij? Tried also with default Zellij theme.

Thank you!

Seeing the same thing on macOS with zellij 0.40.1 (color is slighly darker for text with curly underlines and the rest of the line after that, but only in zellij).

Edit: I was able to fix the issue for me by upgrading my terminal program.

Some more detail: I was using iterm2 with a custom .terminfo file for "xterm-256color" to enable "undercurl" support (See https://gitlab.com/gnachman/iterm2/-/issues/6382). The issue went away after switching to iterm2 beta and dropping the custom .terminfo file.

Interestingly after update to nvim 0.10 the undercurls are displayed correctly in Windows Terminal outside of Zellij.
In Zellij now they are displayed like regulare underlines, at least without the color issue.

Here are some additional test results, done on wezterm nightly: sainnhe/gruvbox-material#205 (comment)

preferably, there would at least be a consistency that neovim under zellij displays uncolored curls as well
