Thanks.  This shows that we have to deal with an increasing number of
window managers that pay more attention to size hints than we have
bargained for.  If Emacs doesn't keep pace with that development,
leaving 'frame-resize-pixelwise' at nil will become an obsolete option
soon.

Did this happen with emacs -Q?  An optimized build probably?  Also the
line numbers do not really correspond to neither emacs-29 nor master as
I can check from here via savannah.  In either case, dumping traces to a
buffer can produce all sorts of problems, although I try hard to do that
in "safe" places only.  So it might be related.

Now I'm confused.  How on earth do we scale with Lucid?  If we do, then
please show me how Lucid handles the Inconsolata scenario.  And please
try also the Inconsolata scenario with a GTK build and the new code.  I
doubt that the code can handle it out of the box but maybe we can tweak
it sufficiently.

Thanks, martin
