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.
