Hello,

When using frappe variant and trying to select text it is almost impossible to see what text was selected.

Using set -gF mode-style "bg=#{@thm_surface_2},bold" make the selection much more visible

Not when using catppucin frappe theme for kitty (outside of tmux) the selection looks like this

It seems like there are some difference between the tmux and kitty theme regarding styling of the selection
