Because of rounding. Tool bar, menu bar and scroll bars do not have
necessarily sizes that are multiples of a frame's default character
size. And often you're losing pixels when the frame gets maximized or
‘frame-resize-pixelwise’ is non-nil during resizing.

Everything that counts in pixels like ‘frame-pixel-height’.

Indeed.

Not here. I get 648 and 44 in both cases.

So your frame has grown by 90 pixels. Remarkable. BTW setting
‘frame-inhibit-implied-resize’ to t would avoid that.

Here all lines are the same, again.
The problem is not GTK specific. Lucid and Motif behave similarly. I
suppose that just enabling ‘tool-bar-mode’ is not sufficient to make a
gnus tool bar once gnus has started. Maybe this deficiency is inherent
to ‘tool-bar-mode’ itself. But it would be interesting to find out
who's responsible for making such small (8 pixels in your, 35 pixels in
my case) tool bars in the first place.
