I actually just installed adrenaline 19.1.1 as well. I have the RX 570, once installed, it kept turning off my monitors (I have 2 monitors connected to the GPU) after 10 to 20 mins of minimal usage. I uninstalled 19.1.1 using DDU, and downgraded back to 18.12.3. It's working normally again, i think this new "updated" driver has so much bugs, I hope they fix it soon.
