GPU/Stack RX 560/amdgpu/linux console
CPU: R7 2700X
Distro/Kernel: LFS/5.1.5

I have been experiencing what appears to be the same issue on any kernel newer
than 4.14 that I’ve tried. I had been running Manjaro 4.14 which works fine,
but I briefly tried LFS and discovered this issue. I’ve tried some different
kernels, but all the ones after 4.14 exhibit the same issue. 

The video shows a single flicker, but the flickers occur fairly regularly when
scrolling.
