Vega 56 - Windows 10 Desktop lagging while gaming in windowed mode.

While playing a game like GTA V, it happens in other games also but GTA V does it the worst out of the games I've played so far.

If I set the game to full screen windowed mode or windowed mode, everything out side the game almost completely freezes, to the point windows explorer, desktop manager will sometimes crash, & lose all the icons, background & taskbar.

 

Here is the part that drives me crazy, if I set the game to run while unfocused, when I target another window off the game everything works fine, the game keeps running as normal & the desktop works fine but as soon as I target the game everything else freezes up. it's like when focused the game takes high priority of the GPU. I don't have windows 10's "game mode" on. even if I'm playing a game like WoW & the GPU usage is only around 60-70% if I have video playing back on one of the other displays it will shudder & drop a lot of frames, focusing a window off the game & everything goes back to normal the same as with GTA V.

I recorded the issue, when the game is focused the video playback on 2nd display pretty much comes to a halt & after a bit the windows background goes black on the 3rd display.

 

I looked in the Radeon settings, I don't see anything about focused window, game priority.

 

I was using a GTX 1060 in my system before this, I never had this issue until I replaced it with the Vega 56.

 

Does anyone have an idea on what it might be or how to fix it?
