I found a thread in the archives from back in 2009 saying this issue was fixed:
http://www.mail-archive.com/fvwm-workers@fvwm.org/msg01957.html Yet in fedora 17, GIMP sets WM_NAME and _NET_WM_NAME to utterly different strings, and I'm getting the (useless) WM_NAME string rather than the (useful) _NET_WM_NAME string. Did this revert in later versions? I have: fvwm-2.6.5-1.fc17.x86_64 See this bug for details: https://bugzilla.gnome.org/show_bug.cgi?id=684239
