AMD Driver 19.7.2 is working as good as was 19.7.1. I detect no issues, no flickering, no disappearing devices, no glitches etc. New driver works really good and anti lag feature really gives some nice stability and smoothness to the games. I decided to make a thorough research over my laptop settings, as it is clear to me, that issue we experienced is not a result of the driver itself. Think about it. We all have the same hardware configuration, which means that driver is implemented the same way for each and every one of us. Or should I rather say, "It should be implemented the same way". Obviously it is not. My conclusion is, that if after trying every possible solution with the driver, you still get the same result, which is persistent failure of device working properly, the problem is not in the driver. Why would it work perfectly fine for other people but not for you? To me it is clear that the fault is on the side of Microsoft. It wouldn't be the first glitch that they created in their history and definitely isn't the last one.
What I am trying to say, is this: most likely settings of your OS cause the failure of correct implementation of the driver.
I will give you now precise description of the path I took to update driver, including my windows power settings, cause I certainly believe the problem lays there. Please try and let me know how it works for you. If the glitch will remain also let me know, so in that case I will do some more checkup and try to find the solution for you guys.
Attention! Make sure that before you start, you are not plugged in to internet and that you disabled driver auto update in windows option. This is very important!
Lets get started with windows power setting.
1. Right click battery icon on task bar and left click power options. Make sure that your checked power plan is high performance.
2. Left click "change power settings" to the right from active high performance power plan. Change "put the computer to sleep", both on battery and plugged in, to "never".
3. In the same window left click on "change advanced power settings".
4. In the new window scroll down and left click "AMD power slider/overlay" then make sure that both options are set to "best performance".
5. Next Left click on "switchable dynamic graphics/global settings". I have it set "on battery:optimize power savings" "plugged in: maximize performance". But I am using laptop to play games only plugged in, if you are playing while on battery only, I recommend to swap "on battery" to maximized performance" as well.
6. Lastly expand "AMD Graphics power settings/AMD Powerplay Settings" both to "Maximize performance". Apply changes and close the window.
Now proceed with driver installation following these steps:
1. Using DDU switch laptop to safe mode (recommended) then, after system reboot, uninstall your gpu driver. Your laptop should now reboot back to normal mode.
2. After reboot install chipset driver that I provide in the link to my gdrive (for the reason I do not understand, asus has removed most recent version of the driver (2520141501) which was published on july 17. In my case this driver fixed the issue, cause I had same problem as all while using previous version of the asus driver. Link at the end of this post. To install the driver properly you need to right click "install.bat" file and open it as administrator. If you double left click it, the cmd window will open and process of installation will proceed, however driver will not be properly installed. This is very important, cause it's very easy to overlook this step. If you rushed and double left clicked no worries, redo the procedure by right clicking. I tested if it works and it does. Just make sure you install this as admin at least once 
. Reboot.
3. Now get amd driver 19.7.2 if you didn't download it before and install it. I tried both express and custom install and both works just fine. If you custom install make sure that you know what you are doing 
. After installation reboot.
4. After restart, open device manager window and go to display adapters. Expand it to make sure that there is no error. Even if there is not, right click 560x and chose update driver, then use option to install driver from your hard drive and chose directory where you unpacked the driver from amd. If you haven't changed driver destination during installation process, it will be on C:/ AMD (I recommend to don't change anything while installing AMD driver to avoid searching for packages in case something will go wrong). Proceed with driver update, if everything is OK, you will get response that the newest driver have already been installed. Be sure to do that, cause sometimes for no reason. driver fails to install and this is the best way to make sure that you have what you really want to have installed. In case the driver failed to install correctly and manual update implemented it, make sure that before reboot you will do one more amd 19.7.2 installation, but this time do not use express install, only custom! Leave everything as it is and proceed with installation of the driver and all components that were auto checked. Reboot. Test.
If I was right (pretty sure I was ) your problems are all over and you will no longer experience disappearing rx560x glitch.
I sincerely hope that this is the end of the problem. I will be looking forward to your responses to see how it works for you. In case it doesn't solve the problem I will dig some more to find out what setting in my laptop makes it work perfectly fine and without the glitch that you guys still suffer.
In the end, if this solution will solve your problem, I will appreciate if you hit the like button under this post and mark it as helpful (also I will be happy if you can follow my profile and throw me some "thank you" badges there ).
Here is the link to the driver mentioned before:

And here is link to AMD driver that I am using without any problem:
I don't think it would work. Had tried with 19.7.1 and guess what ?! Even Vega 8 disappeared 
Tried cleaning and got stuck in a loop , everytime the system would start in the safe mode , and after 10 to 15 seconds a dialogue box would keep on appearing which had the title Microsoft Windows and read , "This application has stopped working...". Had to reset. And then I sticked to the asus driver.
Gonna get my replacement product by the evening I guess. Gonna try it your way this time.
