i've tried older drivers such as 22.214.171.124, 18.12.1,18.9.3 and there is no problem on these drivers.
i've tried to disable radeon overlay, does not work.
i've tried to disable upgrade advisor, does not work.
i've tried to enable VSR, does not work.
i've tried to disable GPU Scaling, does not work.
i've tried to change scaling mode and non of them does not work.
i did uninstall all the drivers with DDU in safe mode.

I have the same problem alt tabbing to Desktop from Company of Heroes 2. I can confirm this is the case with my RX 570 4GB as well as my RX Vega 64. Sometimes the alt tab will work but others the display on my primary cuts out and i have to manually put the primary display's DP into another socket on the GPU and I will get my screen back. Sometimes, both my monitors go black and I can still hear system sounds. This has been happening for the past few driver revisions.
Windows 10 64bit
AMD FX 8300
MSI 990FXA-GD80 V2
16 GB RAM
Vega 64/RX 570
running drivers 18.12.3
Exactly the same problem (vega 56).
When I turn off FreeSync no problems.
Be sure to report the problem inside the radeon driver under preferences > report problem (or something similar using other language).
I had to uninstall and go back to 18.11.2.
Both 18.12.2 and 18.12.3 drivers were causing all 3 off my monitors to tun on and off when opening simple applications like Chrome or task manager. I tried running Malware bytes, uninstalling audio drivers, resetting router, turning cables around and unplugging just my main MSI MPG27CQ 144mhz monitor. All to no avail.
Finally, found out both drivers are just severely bugged. Here's what I am running:
Powercolor Red Devil 64 Vega (No OC)
MSI MPG27CQ (main)
Samsung C27F398 (secondaries)
I hope AMD will help and fix this with their next driver update.
I have same problem with RX Vega 64 Liquid with both Adrenalin 2019 18.12.2 and 18.12.3, frequently accompanied by black screen, audio buzz and PC freeze on Windows 10.
yeah still exists in 19.1.1
vega 64 8gb
these are seems like fixed but these are not fixed at all.
still exists in version 19.1.2
BTW,I found that this problem only occurred in the DP port, HDMI is not a problem.
Yesterday I've installed brand new RX 590 into my brother's PC and encountered pretty much the same issue. With 19.1.1. and 19.1.2 drivers, black screen occurs at Windows logon, while alt-tabing from games, using ctrl+alt+del shortcut (even on desktop) and even when UAC is triggered in Windows. Seems like monitor is losing connection with GPU for like a one second and then input is reconnected (because monitor displays DislayPort input notification). However, when freesync is enabled in monitor settings it gets much worse, input does not come back automatically, I need to manually select it in OSD or turn monitor on and off. this renders freesync basically useless and that is the main feature that made my brother buy AMD card in the first place, even though Nvidia gpus supposedly support it now too - we expected better support with Radeon. That said 126.96.36.199. driver works flawlessly.
Here are his specs:
AMD Ryzen 1400 @3.8 GHz
8GB DDR4 @3133 MHz
MSI B350 Tomahawk
BeQuiet Pure Power 11 CM 600W
Windows 7 SP1 + all updates
Samsung c24fg70 144Hz connected via DisplayPort
I'd really like AMD to at least acknowledge the problem and fix it in the near future 😕
