Nope, there is no fvwm bug, it is just that an unitialized variable may reuse the values from the previous calls. When the window has no title, frame_get_titlebar_dimensions returns immediatelly, and title height stays unitialized although you access it.
Oops. Somehow I overlooked this. Mea culpa.
I rewrote the patch, so it does not call this function at all and in the same time works correctly with title-less windows.
Great. Thanks, Mikhael! Regards, Evgeny
