< This requires Vim to be built with the |+vtp| feature.
Note that the "cterm" attributes are still used, not the "gui" ones.
+
+ When using Vim with Windows Terminal, the background of Windows
+ Terminal is normally filled with the Vim background color. Setting
+ 'termguicolors' and the guibg of the Normal highlight group to NONE
+ will make the background transparent: >
+ :hi Normal guibg=NONE
+<
NOTE: This option is reset when 'compatible' is set.
