QPushButton resizes after color change

Question

I want to change the background color of QPushButtons. The problem is that changing the background color using setStyleSheet("QPushButton { background-color: #00FF00 }");, the button size also scales.

before

after

I understand that by changing the background color, the entire button stylesheet is overwritten and reset to default ( How to override only one pair of properties: value in Qt StyleSheet ).

My question is: how can I set the button size so that it is the same size as the original?

I use MacOSX and I have tried all combinations of height, minimum height, indentation.

               " px; " +
               "max-width: " +
               QString::number(ui.pushButton->size().width()) +
               " px;");
QString height ("min-height: " +
                QString::number(ui.pushButton->size().height()) +
                " px; " +
                "max-height: " +
                QString::number(ui.pushButton->size().height()) +
                " px;");
