colorscheme wpgtk highligts all slashes and brackets

[quunnb]

set noshowmatch or :NoMatchParen has no effect.
Also tried :hi MatchParen ctermbg=none and let loaded_matchparen = 1

wpgtkAlt is working correctly:

I'm not able to reproduce this. Have you set the t_co variable?
This is what I have on my .vimrc

" color options "
"""""""""""""""""
set t_Co=256
colorscheme wpgtk

I'm sorry, my setup has transformed to something without wpgtk. I'll get back to this if I ever switch back, thanks 🙏
