Qt has a bug QTBUG-72558, which leads to incorrect progress bar position, when drawing it in delegate. Also, since OS X 10.10 Yosemite macOS default style was changed, and progress bars became very tiny and without text (percentage). These two cases make qBittorrent look pretty awful, but drawing progress bar in Fusion style solves both issues.
