If the taskbar is not drawn on top of the Z-order stack then maximising a window will draw on top of the taskbar (which does not mimic native MS Windows behaviour). I've tested out a few scenarios, with a small C++ test program (compiled with winegcc) which simply draws a window. One the tests being to maximise the window.
That shouldn't happen at all. Maximized windows should fill the workspace, which specifically excludes the taskbar.
Unfortunately it does though. I remember discussing this issue, probably on the WineHQ forums, with an other user having similar problems. So I'm not the only end user to experience this issue with DOOM 2016. The taskbar appears to capture focus when a player is moving around in game e.g. looking up and down with the mouse. Possibly when the virtual mouse hits the bottom pixel of the screen?? The end result is that you can't move in game at all and basically have to exit the game completely (e.g. switch virtual desktops or switch to a virtual TTY console).
