This looks like a minor performance issue. Do you agree Gabriele?

Yeah, there's not much we can do here. The button color is changed by setting its active property via CSS. When the user taps a button the layout engine will schedule an event to repaint that element as soon as it gets a chance. However, since we're drawing the numbers at the top of the screen which will keep it busy, when the users taps quickly by the time the layout engine can catch up the button will not be pressed anymore and thus the repaint will be discarded.

To improve this we'd need to significantly refactor the callscreen CSS and layout to ensure quicker painting but that's not an easy task and hard to justify for such a minor issue.

Per comment 5, the tradeoff doesn't worth it.
