Search-highlighted characters become unreadable when a vertical line is over them.

[ghost]

Whenever a highlighted, due to hlsearch, character is overlapping with the cursorcolumn or colorcolumn colum, both its foreground and background are darkened. This only happens for characters not in the same line as my cursor.

I'm using rxvt-unicode-256 and

set hlsearch
set t_Co=256
let g:hybrid_use_Xresources = 0
colorscheme hybrid

Good, this is exactly the same issue I have. I have recently asked a question here:

And I still have no clues...
