Created attachment 112511 [details] Falkon switching to foreground I have learned that Falkon won't behave like Firefox or Chromium from the bug #392805. Therefore I have added a Window Rule for Falkon allowing it to steal the focus. But in one case it didn't: 1. select other windows in foreground 2. click on "Show Desktop" applet 3. Open a URL. I was expecting Falkon to be in foreground. But it didn't. It could be a bug in the "Show Desktop" applet / KWin.
From the video we can see that falkon does not even try to activate it's window. If it would, KWin would either activate it or pass it the demands attention state. Neither happens as we can see in the taskbar.
It does call QWidget::raise() + QWidget::activateWindow() in both cases on the video though.
