Border-Radius is not working with QProgressBar when value is 0.

[IRADA]

Hello,
I'm using a ProgressBar for a timer but when the Width of the ProgressBar is less than the border-radius, it defaults to no border radius and shows a square.
I tried to do it with a slider instead but that did not work either.
Can I fix it somehow with CSS?
Or maybe there's a workaround with a mask possibly?

Pasting some working code is always a good idea.

@Markkyboy my bad I didn't think it was necessary as It's a known CSS issue

However I fixed it finally by using a Bitmap the same dimensions as the progress bar and setting it as a mask for the progress bar

        bm = QBitmap(self.min10.size())
        bm.fill(Qt.color0)
        p = QPainter(bm)
        p.setRenderHint(QPainter.HighQualityAntialiasing)
        p.setPen(Qt.color1)
        p.setBrush(Qt.color1)
        radius = 21
        p.drawRoundedRect(QRect(0,0,bm.width(),bm.height()),radius,radius)
        p.end()
        self.min10.setMask(bm)

Thanks to a bug report from a decade ago

Here is the result
