Hi @VladyslavLukyanenko, thanks for reporting the bug. Could you provide a minimum reproducible code?

Clone wishlist, run it using go run -race . serve there's a lot of race conditions but this one happens upon shutting the server down/exiting it

Note: you need to connect to the server and then it happens, launching it and closing it won't trigger it

Could you test this with these branches muesli/termenv#146 charmbracelet/lipgloss#210?

so the other data races are completely gone, thanks for that, but this one still persists.
