I think gtk(or only glib? anyway) works strange with 8-bit grayscale or
staticgray.

When I run gtk app on 8 bit gray X with other applications like xterm,
screen looks strange. when I switch focus on gtk app or others, other
windows not focused look strange.

Especially when I use a window manager not using gtk(for example, twm,
windowmaker, mwm), it is really unbearable.

Do you have any idea to solve it?

Thanks.
