Imho you tracked the issue to the wrong line in your code. The issue
is more likely caused by
https://github.com/wedesoft/hornetseye-xorg/blob/master/ext/x11window.cc#L255
(haven't checked though) which in turn refers to
https://github.com/wedesoft/hornetseye-xorg/blob/master/ext/x11window.cc#L251,
which might not exist (due to the True as last argument) in case of
dwm. dwm doesn't use or set any MOTIF hints.
