Gigabyte Radeon 5700 8gb using HDMI ultra wide monitor. Windows 10 PRO (aka Skynet) I7 9700K octa core and 16gb ram with a single SSD with the OS and the games on it. PSU Corsair tx 750. I use it with a single wide screen LG monitor with its original HDMI cable. I'm not sure where to place this issue so I'll just leave it at graphics location, but it can be drivers both card and/or OS.
The weird problem I'm having :
While playing games on full screen mode, the game or something else forces the screen to switch to windowed mode exposing its borders, swapping screen modes by itself. It isn't resizing the resolution, only changing its modes entirely by itself. Sometimes it happens once per 2 hours of gameplay or twice in just about 20 minutes. It is pretty random and it smells like software or whatever, but I wish to know if this is a known hardware issue (I haven't found a problem like mine before posting this) so I can make the decision if I should RMA before my time expires, or if its something else.
Before it happens in a fraction of a second I have a very quick flickering. Most games keeps running just fine and I must hit alt+enter so I can go back to action (it is easy to fix like that) but it is very frustrating when it happens for that reason.
Around February I used to have that even while navigating youtube or something using Mozilla's browser but then it stopped, I don't have it no more on browsers. I don't have that problem with browsers now it only happens with games. The why is a mystery I have no clue off.
What I suspect it to be
I no longer use the Radeon Software or whatever it is called but it happened just like that when I was using it too (I removed it thinking it would help, it didn't) The difference is that Radeon's crash defender used to warn me about drivers taking too much time to respond or something like that when that screen resizing happened.
I don't remember having problems when I used to play with keyboard and mouse. Before buying a Xbone X joystick and using it with some USB cable so this is also pretty suspicious. I already tweaked everything related to that on Windows, what I'm missing?
Things I have tried
Windows T-800 is always up to date, so yes it is updated. This is something you're taught from birth to keep it that way when you have a nerd family and brains (unless the update is bugged like it is often the case).
I have tried numerous previous drivers from AMD, plus the latest drivers, obviously by purging them first and then reinstalling it clean.
I decided to do the classic things such as tweaking the energy management of the Xbone X in the device manager. I even tried switching the screen saver timing, I was worried that would be what was causing the problem, but nothing really stops it.
I also have tried numerous work arounds I could think off as I described but it still is happening anyway. No fix. Screens keeps swapping by itself anyway no matter what I do. I have also tried selecting 75 herz instead of 60 for my ultra wide screen and then swapping it in-game accordingly. Didn't help either, problem still happens.
How often it happens
I may say in a couple hours of gameplay, now I expect it to happen at least once, but sometimes it doesn't happen at all. If this isn't common issue today with drivers and etc I will consider filing a warranty for I have no idea if that's a faulty hardware. Doesn't seem to have any other issue not even when running games on ultra. It is a shame most games of today forces me to use Windows 10 as the main OS because I also suspect it to be the problem.
I do prevent the initialization of some other softwares I own, some of them would be causing this, even tried shutting Microsoft's antivirus but it didn't work, problem persists. I'm getting tired of this riddle. I can't test the video card somewhere else because I live in the middle of nowhere with nobody in the vicinity for me to check it, but my motherboard seems fine when I plug the monitor on it, can even play easy to run games such as Warframe without any issue.
I couldn't find that issue anywhere else so if you know what could be causing that you can potentially help others when they google it around.
Solved! Go to Solution.
It turned out apparently, that my monitor wasn't set for "Free Sync". So the combined settings with higher refresh rate and this fixed the issue. I still don't know why it was happening so frequently when using joystick but at least it is fixed now. No more full screen to windowed mode for days now. Make sure to tweak your monitor accordingly if your case is near but not quite the same as mine.

Thank you for clear information that tends to shot out issues..I got it!!!
NP, sorry for super long text, I did so because the problem was really weird. Sometimes the solution is that small thing we ignored for too long haha.
