Description Owen Taylor 2005-02-03 20:13:45 UTC 
If you create a window without setting WM_NORMAL_HINTS, it might
or might not get a title bar. Looks like an uninitialized variable
reference. This is with metacity-2.8.6.

There is some sort of race condition involved it seems ... I
reproduced it *once* with the attached test case, but it happens
much more frequently with a real app with an expensive expose-event
handler. (pango-xftview from pango/examples run on HELLO.utf8 triggers
the bug more for me. Though I'm about to check in a fix to make
it set WM_NORMAL_HINTS. Checking out on the pango-1-8 branch
will get the program without the fix.)

test case

Compile with

 gcc -o no-title -L /usr/X11R6/lib -lX11 no-title.c -g -Wall

Or something like that.

Cool, I like this testcase better than the one in bug 145131.  Also, thanks for
the hint regarding WM_NORMAL_HINTS.  I had tried to look into this a little
before but didn't have much time...I'll try to dig deeper.
