<![CDATA[QSpinBox behaves strangely when padding is set]]>in QtDesigner, I am styling a QSpinBox with just simply padding: 5px, but this happens when cursor enters or leaves the QSpinBox:

I hope you can see that gray kind of padding surrounding it (since I can't post an .avif which shows better the flickering). I tried manipulating the values exactly as well as demonstrated in qt documentation like this:

QSpinBox {
	font-size: 18px;
	border-width: 1px;
	padding: 5px;
}

QSpinBox::up-button {
    subcontrol-origin: border;
    subcontrol-position: top right; /* position at the top right corner */
    width: 4px; /* 4 + 2*1px border-width = 5px padding + 1px parent border */
    border-width: 1px;
}

QSpinBox::down-button {
    subcontrol-origin: border;
    subcontrol-position: bottom right; /* position at the top right corner */
    width: 4px; /* 4 + 2*1px border-width = 5px padding + 1px parent border */
    border-width: 1px;
}

but this completly hides the up and down buttons and so is the border of QSpinBox and couldn't find any similar issue out there.

I can reproduce it but no idea how to fix it. You might create a bug report -> bugreports.qt.io

don't know what you mean by style

Style: https://doc.qt.io/qt-6/qapplication.html#setStyle
What OS do you use?
