Qt 5.7 drawRect with big stroke width drawing cut out corners

I am trying to draw a rectangle with big stroke width(set by a QPen) and QPainter is drawing the rectangle but all of the corners are a little cut out, not as sharp as they ought to be. Here is an image: https://i.sstatic.net/omAdY.png

I'm drawing it on top of a QWidget using this code: 

m_painter.drawRect(upLeftX, upLeftY, downRightX - upLeftX, downRightY - upLeftY);

Moved from comment.

You can set the pen's join style easily using QPen::setJoinStyle. To modify the pen currently in use by the QPainter use something like...

QPen pen = m_painter.pen();
pen.setJoinStyle(Qt::MiterJoin);
m_painter.setPen(pen);
