I'm seeing an odd X behavior, and am trying to determine whether it's originating in the X Toolkit or in my window manager (fvwm). I also can't tell whether it's a bug, or inexplicably intended behavior, or some weird side effect caused by an X resource or other configuration option. So I'd like to know whether people using other X window managers and configurations are seeing the same behavior.
When I start a program from the command line specifying the X Toolkit
-title option, the argument to that option is typically used as the window title, which is displayed in the title bar. (Two common applications where I might supply this option are
What I've found is that when the string I pass to the
-title option ends in
lock, the window is instead displayed without a title bar at all. It doesn't matter what, or how many, characters come before
lock, only that those four characters be the end of the argument.
That is, the following titles work as expected:
-title test -title locker -title lock. -title lock_master -title lok -title ock -title wock
while the following titles unexpectedly cause the window to be created without any title bar:
-title lock -title flock -title wtf_is_going_on_with_lock
Does the same thing happen on your system? What's your environment? I'm running X.Org X Server 1.16.4 and fvwm 2.6.5.
