I just noticed that the scroll bar size marker (the thing that moves on
the scroll bar) changes it size as you scroll a buffer in Emacs on w32.
I have not seen this in any other program on w32 and it seems to me to
be against the expected behaviour.
Is this something that is w32 specific?
To notice the the effect make the window a little bit smaller than the
buffer and move to the top and bottom.

No.

Scroll bar start and end correspond to byte offsets in the file, and
bytes/line is not a constant but content-dependent.
If we take the Athena scrollbar semantics, this means that mouse-1 and
mouse-3 operate by screen-lines, while mouse-2 operates by byte
offset.
This is not a w32-specific problem.
