QSlider stylesheet handle gets slightly cut off on linux but looks fine on windows

[tjudg]

QSlider::groove:horizontal {height:6px; background-color:red;}
QSlider::handle{margin:-6px; image: url(:/image/handle.png)}

Is there a way to make the slider on linux not slightly cut off the top and bottom of the handle?

I figured it out, it wasn't a stylesheet problem. I had to add

slider->setFixedHeight(20)

and it worked.
