I am wondering if anybody else is experiencing this issue. With a clean install of 10.14.4, my cMP consistently wakes up to a black screen. To get an image, I must power cycle the display. Also, after waking up, if my RX 580 is mildly stressed (like after scrolling pages in Safari) its fans momentarily spin up (quite louder than in 10.14.3) and then spin down (annoyingly pulsating in synchronism with my scrolling). Before sleep, the card behaves normally. I've gone back to 10.14.3 and everything there is fine. Would anybody have any experience with troubleshooting such an issue?
