The following code will cause the problem:
var titleWindow:TitleWindow = new TitleWindow(); titleWindow.width = 500; titleWindow.height = 500; titleWindow.title= "test"; PopUpManager.addPopUp(titleWindow, parent, true); PopUpManager.centerPopUp(titleWindow);
The modal blurring appears, but no popup.
If you wait an unreasonable amount of time 5-10 seconds, it may appear. Otherwise, if I force the window to redraw by switching tabs or resize, the popup appears immediately.
This issue appeared when updating from Flash Player 11 to Flash Player 12.
This is an issue with Chrome's Pepperflash... at the moment we can only disable Pepperflash and enable Adobe Flash for our applications to work properly.
