I place an emacs -Q session and a konsole with xrestop side to
side. Just opening a file, scrolling through, etc, makes the number of
pixmaps and misc objects to grow. Killing the buffer does not reduce the
number of X resources used by emacs. Something as simple as C-x C-f C-g
increases the number of pixmaps by 4 (2 for C-x C-f and two more when I
abort with C-g). Is as if the allocated X resources never were freed.

Could you provide some hint about how to investigate this issue? I'm a
complete X-Windows ignorant, but know the basics about gdb (and I
willing to learn).
