background glyphs unreadable

[brainlessbitch]

i can't see the background glyphs at all, how could i fix this?

The underlying issue might have something to do with terminals and terminfo and ncurses, but it gets fixed with this change to the line 113 of tui_main.c :
case Glyph_class_grid: // attr = A_bold | fg_bg(C_black, C_natural); attr = A_dim | fg_bg(C_white, C_natural); break;
