I believe this is the same issue I had which is a VGA handoff problem.
Can you try this patch the display team sent me?
Harry: Will this patch be promoted in the next cycle?

Hi list,
I'd like to report a very odd screen artifacts while running both
4.16-rc3, as well as latest 4.16-rc4 with git linux-firmware.
I am using Ryzen 2400G with the integrate Vega.
I am aware that RAVEN support is yet to be finished, however I've read
that some people do run it already, so I figured I will report the
issues, since other does not seems to hit it.
I have amdgpu and all it's symbols built into the kernel image, and the
firmware added to initrammfs. The moment modesetting is initializing I
can see that native screen resolution goes, however, I can see only like
25% of the screen and this very top-left 25% of screen is duplicated to
top-right. While the bottom half of screen is either black or have
lines, usually gray, unless some text on screen had another color then
it's green, blue, etc.

Subject: [PATCH] drm/amd/display: Fix takeover from VGA mode
HW Engineer's Notes:
During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
VGA_TEST_ENABLE, to leave it in the same state as before.
