I have this problem on Archlinux 5.2.8-arch1-1-ARCH when connected 2 monitors(1920x1080 @ 60Hz) and amdgpu.ppfeaturemask=0xffffffff option enabled. Patch didn't work for me.
My GPU is RX570.
Try this patch: https://lists.freedesktop.org/archives/amd-gfx/2019-June/036022.html
That patch solved the issue but memory clock is fixed to maximum state(1750MHz). Normally it should change dynamically.
That patch only fixes reclocking behaviour with ppfeaturemask=0xffffffff. I have two 75Hz monitors and flickering only appears when I enable OverDrive. And memory clock is ALWAYS fixed to maximum state in my case to (surprise) prevent flickering =).
