DECRQSS +q5463;524742;73657472676266;73657472676262$qm appears in terminal about neovim HOT 8 CLOSED

Same issue on windows cmd.exe
use nvim --clean to reproduce.

I'm guessing this is due to DECRQSS terminal escapes that aren't implemented by macOS terminal. Apparently alacritty/alacritty#7184.

The terminal should not print an escape sequence just because it's unimplemented. This is just Apple Terminal being terrible, as usual.

We disabled DECRQSS for Apple Terminal in #28453, but that won't work for a remote SSH session (the remote session doesn't know anything about the terminal emulator). We are also sendin XTGETTCAP and DECRQSS requests to determine truecolor support in _defaults.lua, where we don't have any guards for Apple Terminal.

A workaround in the meantime is to set COLORTERM=truecolor in your remote environment and also use set notermguicolors in your init file. Setting $COLORTERM this way will prevent Nvim from querying the terminal (it will assume that the terminal does support truecolor), and then disabling 'termguicolors' in your init file will disable it again.

I'm certain this is discussed in existing, closed issues.

Don't use Apple Terminal, it's plain broken. iTerm2 (3.5, the betas are release candidates now) will do in a pinch.

I'm also seeing this on PuTTY 0.81

If #29197 is applied then you can opt out of the DECRQSS/XTGETTCAP queries by setting $COLORTERM to any value other than truecolor or 24bit (e.g. 256 or 16).

Thanks for that PR, @gpanders . I see the PR mentions that setting $COLORTERM to truecolor or 24bit should prevent the terminal from being queried. However, I've found that when setting that, I no longer see $qm463;524742;73657472676266;73657472676262, which is great, but I still see +q4D73 pop up briefly. This is on PuTTY 0.81.

That is the OSC 52 query. Set vim.g.clipboard = false in your init.lua to disable it.
