Comment # 18 on bug 103791 from Anthony Parsons

Hi, I'm seeing the same problem on an RX550 (polaris12). Running xrandr doesn't
seem to work as a workaround but flipping VTs does. Would having the debug
output for this one be useful, or was the other log enough?

kernel 4.14.5-zen+
xorg 1.19.5
xf86-video-amdgpu 1.4.0
libdrm 2.4.88
