Thank you. The trick is to disable the mouse support for Vim. I achieved this by adding the following to the /etc/vim/vimrc file.
I had to add syntax on to enable syntax highlighting.

set mouse= 
syntax on 

This way ends with text copied to clipboard with line numbers, Of course if you have one window vertically. Instead I used to this option. JUST HOLD SHIFT KEY DURING SELECTING TERMINAL TEXT TO BEHAVE LIKE set mouse-=a

Thanks, it's working :)

For anyone trying to figure it out on Debian 12 after moving from CentOS, here is what you can do by combining all above information and checking what /etc/vim/vimrc is doing:

• create /etc/vim/vimrc.local with following content:

unlet! skip_defaults_vim
source $VIMRUNTIME/defaults.vim
let skip_defaults_vim=1
set mouse&

In this way, visual mode on mouse select will be disabled but default configuration still loaded and this config will survive vim upgrade.

still a life safer in year 2025.
Thank you.
Happen in wsl debian too.

If only this worked for IdeaVim. What a pain.
@ixtk

it works like this:

set selectmode=mouse,ideaSelection,
