that's how your theme color codeblocks I guess, you can maybe confirm in a markdown buffer, where you can add a code block and maybe will behave the same?

BTW I don't see anything weird 😅 it's a good idea use a different color for code background to know that it's a code inside that block

Oh I mean, what's weird are these: The first lines seem to be off by one below lol

oh got it, I saw that issue somewhere else

it's from lsp-mode indeed

Search on lsp-mode, you may find a issue somehwere else complaining the same

Ah, cool. Thanks!
