It happens actually when I move the mouse from one glyph to another. Now it
is not always repeatable to the point that this always happens if I move
the mouse from glyph X to glyph Y. But I can reproduce by doing this:
"frantically keep on moving the mouse across all the minor mode lighters
(which I have modified to be a single unicode char each)".

Kaushal, did you actually click on those empty parts, or just having the

No, just hover. In that GIF, you will see a small ripple appear around the
mouse pointer when I click.. you see that when I click anywhere in the
buffer to restore the line numbers.

Yes! I believe the problem goes away if I set x-gtk-use-system-tooltips to
nil.
