Just started with the adrenalin update. I have an RX460, desktop, windows 10, Adrenalin 2019 edition 19.4.1, HP 2511x native res is 1920x1080, trying to use 1444x1080, i7 870, 8gb ram. I've never had this issue until I updated to Adrenalin. custom res is set to same hz as monitor but when I set the custom res on my desktop about 1/4 of the screen is black. If use hdmi scaling to 1% in radeon settings it goes full screen but the resolution is off and video is choppy.
