Tooltips and the toolbar are not nececessarily related to each other.
Most entries in the mode line have a tooltip whose left edge should
appear right under the mouse pointer when it hovers over an entry.  The
popup menus should appear centered under the mouse pointer instead.  Can
you roughly describe the relative positions of tooltip and menu for your
mode line entries?

To the right of what - the left edge of the display or the left edge of
the Emacs frame?  Also IIUC x- and y-offsets are affected: Are they off
by the same amounts or proportional to the size of the display?

What happens when you hold the Ctrl key together with a mouse click to
show the Buffer or the Major Mode menus?  Are these menus off as well?

Could you try with an older Emacs?
