@mjaga Just in case somebody wants to test this, here is a minimal example demonstrating the problem:
#include <QApplication>
#include <QProgressBar>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
a.setStyle("plastique"); /* working... */
// a.setStyle("cleanlooks"); /* working... */
// a.setStyle("Windows"); /* working... */
// a.setStyle("Fusion"); /* working... */
// a.setStyle("gtk2"); /* NOT working! */
QProgressBar pb;
pb.setMaximum(0);
pb.setMinimum(0);
pb.setValue(0);
pb.show();
return a.exec();
}
