Whenever you see an inconsistency between what Emacs thinks its WM hints
are, and what you think the window manager sees, try to actually read
the window manager hints property with `xprop'.

It should print several lines describing the window manager hints.

WM_NORMAL_HINTS(WM_SIZE_HINTS):
                program specified minimum size: 34 by 55
                program specified resize increment: 8 by 17 <------
                program specified base size: 34 by 55
                window gravity: NorthWest

Check there to see if the increment is really 17x37.
Xt sometimes refuses to set hints, which can be very confusing.
