Rounded icon separator not rendering correctly

[Kristijan]

Hi All,

I think I've followed along in getting my configuration 2.0 compatible, but I have an issue with the rendering of the separators.

I've tested it both using Warp and iTerm2 terminals on macOS, along with two different nerd fonts.

Any thoughts as to where I may be going wrong?

Hey! This is caused by setting set -g @catppuccin_status_background "none". Without a background color the separators can't be reversed into something useful.

[Kristijan]

Awesome, that's done it, thanks @kjnsn!

I was going for the transparent status look though. So would this be considered a bug (happy to raise an issue if so)?

[Kristijan]

It's a bit of a hack, but I've gotten around it by setting set -g status-bg "#000000" after TPM has loaded catppuccin. The rounded edges are slightly grey, but it's not all that noticeable.

[kjnsn]

Yeah feel free to raise an issue. I think it might be possible to use SGR 39/49 codes to "hack" around this
