This is 100% reproducible, check the gif.
Normally, when you hovering mouse pointer over an item the item information tooltip appear.
But if you ctrl+clicking on a map, the next map you hovering after ctrl+clicking sometimes (quite frequently) doesn't display the tooltip unless you move the pointer outside of item borders.
This happens in every inventory slot in any item transfer direction.
I've noticed this misbehavior since like 2-3 leagues ago.
Thanks for your report, we'll look into this.
