The same problem could be reproduced with fltk-1.1.9 using test program test/color_chooser First run color_chooser without arguments, it displays available visuals: $ ./color_chooser usage: ./color_chooser <switches> visual-number - : default visual r : call Fl::visual(FL_RGB) c : call Fl::own_colormap() # : use this visual with an empty colormap: 35: TrueColor 24/32 8r8g8b (default visual) 36: TrueColor 24/32 8r8g8b 37: TrueColor 24/32 8r8g8b 38: TrueColor 24/32 8r8g8b 39: DirectColor 24/32 8r8g8b 40: DirectColor 24/32 8r8g8b 41: DirectColor 24/32 8r8g8b 42: DirectColor 24/32 8r8g8b 67: TrueColor 32/32 8r8g8b Then choose the 32bits visual (here, number 67): $ ./color_chooser 67 And you get an awful window. You can try to choose different color: dark color are fully transparent, light color are less transparent. This is not a correct behavior. Opacity must be complete by default (no transparency).
