Setting catppuccin_status_background to "none" show 'ugly' rounded separators around Status Session

[codeRSH]

I did search for a similar issue, but couldn't find anything matching exactly with my issue.

Issue 1

When doing :
set -g @catppuccin_status_background "default"

This looks fine, but the background color didn't exactly match the terminal colors, so I tried to make the tmux status background color 'transparent'

But, when doing:
set -g @catppuccin_status_background "none"

Now, the status background color exactly matches the terminal color. As you can see when setting the status background color to 'none' i.e. transparent the separators around Status session modules are showing weird black/white colors. There is no such issue around Modules on the right hand side.

Issue 2

While changing the background color and doing refresh of the tmux config works fine within the current session, but changing the Catppuccin flavor doesn't work either after tmux config refresh or even after detaching and reattaching to the tmux session, or even creating a new one. Only way I can make the 'flavor change' work is by doing a tmux kill-server.

I am currently using iterm on MacOS, but both issue prersists across other terminals like Wezterm and Alacritty.

Paste your configuration.

Here is same issue in Latte Flavor.

What tmux version are you seeing the issue on?

tmux 3.5a

Regarding issue 1: This is well known, see #409, #435, #430, #454. I do not have the time to fix it myself, however PRs are welcome.

Regarding issue 2:

You have not written your config file correctly. I've just put together a guide, take a look at https://github.com/catppuccin/tmux/blob/main/docs/guides/troubleshooting.md#my-options-are-not-being-applied

If that doesn't solve the issue please let me know

Thanks for the help.

I went through all the steps Pointed

1. Completely kill tmux and restart (killall tmux). - Done
2. Ensure every @catppuccin.* option is being set before the plugin is loaded. Loading occurs where you have run in your config file. - Done
3. Double check for typos. There are two "c"s and two "p"s in "catppuccin". - Checked. NA
4. Do not use -o to set options that begin with @. The -o flag means that the option will not be set if it has already been set. You do not need this in your config file. - Checked. NA
5. Double check that any option that does not start with @ is set after the plugin is loaded. - Done

However, it still didn't resolve my issue of 'instantly' reloading the new flavor. I still have to kill tmux and restart for the flavor to apply.

Here is my updated tmux config:

# Set terminal to support 256 colors and true color

Glad the guide was useful! Changing the flavor while running requires a couple of lines as described in #426
