Windows 10: Alt-Tabbing from Fullscreened games causes unaligned cursor

So I noticed this when right after I downloaded Windows 10 that when I alt-tab from video games on fullscreen and alt-tab back in, my cursor will read slightly to the left of where it actually is on the screen. What I've noticed when I alt-tab is that all my maximized windows on the desktop are also shrunk about as much as my cursor is off while in game.

System Spec

Computer typeC/Desktop
OS:Windows 10
CPU:AMD FX 6300 6core
Motherboard:MSI 970 Gaming
Memory:8G
Graphics Card(s):AMD Radeon 7700

I am also using the AMD Catalyst Control Center program to make my desktop fit on screen, as I'm using a 32inch Samsung flat screen as my monitor at the moment. Resolution set at 1920x1080.

If you need any other information at all, I'll try my best to get it to you. Hopefully someone has an answer or at least an explanation!

Issues with brightness and mouse

Original title: Alt+Tab ignores fullscreen?

I have been using windows 10 since I got this new computer and it has worked perfectly fine. Until the anniversary update recently. I play games in fullscreen and I usually alt+tab pretty often to look at other things in chrome and such. It was always a
slow alt+tab on a black screen like it should be, but now it is an instant alt+tab like my game isn't fullscreen. This sounds great, sure, but it causes a lot of problems with things now.

My first problem is that some games I play have the brightness / gamma raised in game so I can see better. When I alt+tab the brightness carries over to my desktop which makes it very bright on my eyes. When I then alt+tab back in the game it removes the
brightness setting completely in game which I then have to reset back to what it was. This happens every time I alt+tab, which is often.

My second issue is mouse delay. Fullscreen doesn't cause mouse delay (not sure the reason behind it, but it doesn't). But now, since it doesn't seem to think my game is in fullscreen anymore I have a lot of mouse delay as if I am in windowed borderless mode.
I've tried changing my settings off and back on to fullscreen and such but it does not fix it.

Thanks ahead of time.

Edit: It is also not just one game, it is every game / every program.

 

I have a game (CrashDay redline), and i can't Alt+Tab, alt+F4, Ctrl+Alt+Delete, Ctrl+Shift+Esc , because it causes freezing

So, I have a game (CrashDay redline), and i can't Alt+Tab, alt+F4, Ctrl+Alt+Delete, Ctrl+Shift+Esc because it causes freezing. If i do any of those combinations - game just freezes forever (all those combination dont work if it freezes), until i hold power-off
button. There would be no black screen, just a frozen game "screenshot". That means - I cant swich window while playing it by doing Alt+Tab or Win+Tab. Just Cause 2, for example, works great after i switch to browser by Alt+Tab and than back to the game.

Problem is not just in crashday, but in some other FullScreen games (and not only for me - for most people). Those apps are old and would not get updates. Is there any fix to that? (Windowed mode is not solution because my screen is too small to work in
a window).

Also a malware could have done that so it should be fixed in windows
