How I solved games from Stream randomly minimizing
I found the reason why most of my Steam games were just randomly minimizing, after trying almost anything, including uninstall and clean all leftovers from Steam and re-installing everything again.
The solution, at least for me, was quite simple.
I use a program called Bluestacks, this is an Android Emulator for the desktop. You can hop over to their website to find more about it. When you install this software you also installing something called Bluestacks Notification Center, this is what allows the emulator to display notifications on your desktop if your logged in with your google account onto the emulator.
Uninstalling this seemed to solve the problem. I use a program called IObit Uninstaller, this software helps clean all the files left by the software, as well all the key entries left behind. There is a few programs like this, just Google for uninstaller and you will find a few.
This easiest way of find out which program is causing the problem is by going to the Startup Manager, you can do this by going to the Start Menu and typing msconfig and then Enter. On the startup tab you will find all of the things that boot up on your windows start.
By disable some of this software that you actually don’t need, you might also find what is causing the issue, as reported by some on the Steam Comunity.
Also on this tread from Steam you can find somethings that might help diagnose and solve the issue.
I hope this helps someone, that is having the same problem, since it’s quite annoying having a game minimize without any reason.
