Kakoune editor shows incorrect colors

[chrisboyce]

When using kakoune from within a zellij instance, the terminal does not show the expected colors. Attached towards the bottom are screenshots of kakoune without zellij (the tan color) and within zellij (the dark blue).

From the kakoune Discord chat:

Kakoune by default uses a palette-switching method to get true colors (outside 256 terminal ones), which might not be working well with zellij. There is an alternative branch builtin-terminal-ui that uses 24-bit color sequences directly, assuming that the terminal supports it. Last I saw it mentioned (#385) it is supposed to be working well with zellij, so you can give it a try.

If I build kakoune from the builtin-terminal-ui branch as suggested, zellij does show the expected colors.

Looking through the commit history, I think that #453 fixed the issue for some people. However if I check out 1f88b34 I'm still seeing the issue, so I don't think this is a regression.

Hey @chrisboyce - this is now fixed in main. Thanks for the report! I hope to release a new version with this sometime next week. Will close this now - if this still happens to you in the next release, please ping me and I'll re-open.
