Taskbar and Close,Minimize,Maximize "pop up" in Fullscreen mode


Hi all
I noticed the problem when i watch flashplayer movies in Edge or use the desktop-app/Win10-Store-App Netflix.
Flashplayer movies on Firefox works everything fine - as expected.

But in Edge or Netflix when i move the mouse to the bottom of the screen the taskbar appears and when i move the mouse in to the upper right corner then the close,minimize,maximize "bar" appears.

My taskbar is not autohidden and i want it to stay it that way. But in fullscreen mode there shouldn't pop up the taskbar anyway, unless i exit the fullscreen mode - like it works in Firefox and like it worked for every application on Win7.

I read a lot about taskbar popping up and even staying always on and i know i had it also once in Firefox. But i think it has something with the new Win10 design to do. And i think this taskbar issue is connected like the issue with the close,minimize,maximize-bar.
Is there some registry key that i can change or a hidden setting?
I will never use the tablet mode or anything like that.
I've 3 computers and it's on all the same.

Thanks for any hint.

 

Taskbar still visible in fullscreen mode

Let's try an attempt at resetting default computer settings by doing simple steps.

1) Right click on the Taskbar, and uncheck Lock the taskbar
2) Click-and-drag the Taskbar over to the left side of the screen, and let go of the mouse click, to set the Taskbar over there
3) Again, now click-and-drag the Taskbar from the left part of your screen right back down to the bottom
4) Right click on the Taskbar, and check Lock the taskbar

Try running full screen applications.

 

taskbar in fullscreen mode

Not sure if I need to put the thread here or in software but as of recently whenever I go to fullscreen mode for a video or game, no matter which application the task bar for windows still shows. I never had auto hide on before and until recently never was an issue. This is a short list of apps that this happens in:
Google Chrome version 55 (youtube, netflix, crunchyroll)
Firefox version 50 (youtube, netflix, crunchyroll)
VLC Media Player version 2.2.2 (locally stored content)
numerous games from Steam with the exception of a couple.
As far as I know there were no windows updates and no additional programs downloaded since it last worked as I wanted it to. As stated above I never enabled auto hide as I know this would solve the issue but I find that more troublesome than this bar. I have windows 10 anniversary update. If more information would help fix this issue I would be happy to assist.
Attached is an example.
