Description
I am not sure if this is a real bug or intended change of behaviour, but at f2de001d8410b85047ee40ebfff1b307a18889bb , the code
QApplication a(argc, argv); QWidget w; // w.show(); QTimer::singleShot(0, &w, &QWidget::close); return a.exec();
hangs. Note the widget is not shown. The app terminates normally when calling show().
The attached sample produces
Qt 6.3.0 (x86_64-little_endian-lp64 shared (dynamic) debug build; by GCC 9.3.0) Timer running
vs
Qt 6.2.0 (x86_64-little_endian-lp64 shared (dynamic) debug build; by GCC 9.3.0) Timer running Exit 0
