Do you mean that it is the popup up menu that takes some time to be displayed when you click on this button?  That might be normal, since there are a lot of symbols in this menu.  At any rate, it will depend on your machine.  Which OS are you running and what is the clockspeed of your processor?

rendering of Bold font button in math-mode is very slow.

I found it is because QTMMenuButton::paintEvent (QPaintEvent e)* has been invoked 155 times for Bold font menu button, each time cost around 0.007s. Cost around 1s in total.

while other buttons in math-mode takes around 0.03s
