Regarding the ESC[?4m problem with vim 9 can you update a temporary version first or is there a patch for that?

Hello @kingToolbox ,
Currently, many servers have upgraded their VIM version to V9, but there is a problem that ESC[?4m(#1623 (comment)) appears when editing a file, although it can be fixed temporarily by the following ways, but it is always troublesome.

Write these into .vimrc:

set keyprotocol=
let &term=&term

Thank you!

This doesn't solve the problem, vim still displays garbled characters.

change Term type to vt520

[moshangluoying]

change Term type to vt520

only work for a short while.
So troublesome.

[bigplaice]

add this line in .vimrc

set t_RK=

It works to me.

The ESC [?4m control sequence (XTQMODKEYS , Query key modifier options) was introduced in vim 9.0. WindTerm 2.7.0 Prerelease 2 now supports parsing ESC [?4m. Please download and try it. Thank you.

@pengln
It looks like you were launching vi within WSL. WindTerm 2.7.0 Prerelease 2 now uses WinPty instead of ConPty to launch WSL. This change should temporarily address the problem you were experiencing.
