Description
Since updating to 3.4.3 via the OSGeo4W updater, QGIS will not move to the top of my window stack over any other app window! Usually I have to manually bring new apps forward after opening them, but nothing will make QGIS appear if another app is drawn.
I've seen this happen to Libre Office (another QT5 app) versus my mail client EverDesk, so I'm not shocked. But QGIS can't appear over any app. And it can't appear over its own sub windows - I'm pretty sure I used to be able to keep those open partly behind the main window...
Taskbar preview shows the QGIS window normally, over an empty desktop. But there is a new curiosity... If I mouse over a tray icon, and mouse away from that icon without touching an inactive app icon, the thumbnail remains visible until I type something in whichever window is topmost.
The QGIS icon background changes when clicked, as if it is being shown and hidden, but it does not appear unless it is the only window displayed.
Windows 10 is out of control sometimes, and all of this may depend upon some recent Windows Update. I don't know how to dig into this window stack mess. I've included the MS Spy++ stack tree, with several groups of QGIS entries way down the stack, including at the very bottom, but I have no idea if there are useful clues there.

One More thing... This is a Microsoft Surface Book, so all the touch extensions and screen scaling mechanisms are triggered. But I've never noticed Z-order problems with QGIS before.
