I tried turn on and off visual effects in Windows, there is no difference about this behaviour.
The effect when the mouse is hovered on a toolbar menu, the background becomes blue and text becomes white is distracting (hard to read the text when the animation is playing).
It would be better if there is an option to use the behaviour like toolbar (the Print button has the mouse hovered), like Windows Notepad:
i.e. only make the background deeper with a rectangle around the button, but not changing the color of the menu text.
