Bisecting points to the following bad commit
fb827c055cb1bdd2b18d0687c06c56b537d805f3 is the first bad commit commit fb827c055cb1bdd2b18d0687c06c56b537d805f3 Author: Nicolai Hähnle nicolai.haehnle@amd.com Date: Mon Sep 12 12:19:47 2016 +0200
winsys/radeon: enable buffer allocation from slabs
Only enable for chips with GPUVM, because older driver paths do not take the required offset into account.

--- Comment #3 from Alexandre Demers alexandre.f.demers@gmail.com --- With the patch, when playing problematic videos, I get a black screen instead of a partial display with green artifacts.
Also, with and without the patch, dmesg catches the following when playing the problematic videos (I should have had a look previously): [76261.125581] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0x8fd80001 already in use!

Should be fixed in Mesa master as of commit 13cb41f666212ed50a7939a37a373b4431a84033. Please re-open if the problem persists.
I still get a black screen when plating problematic videos with the latest Mesa from git as of this morning. And I still get the following error: [...] [ 286.174162] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* invalid reloc offset 13FA000!

--- Comment #6 from Tom neatnoise@gmail.com --- I confirm a bug. It occurs when playing h264 encoded videos using hardware vdpau acceleration. It happens using many players (tested with mpv, vlc), kernel 4.7, 4.8 and current mesa-git.
glxinfo:
OpenGL renderer string: Gallium 0.4 on AMD BONAIRE (DRM 2.46.0 / 4.8.0-rc8-mainline, LLVM 4.0.0) OpenGL core profile version string: 4.3 (Core Profile) Mesa 12.1.0-devel (git-1d466b9)
dmesg messages while playing videos:

--- Comment #8 from Nicolai Hähnle nhaehnle@gmail.com --- Now that I actually got to test this on radeon rather than just amdgpu, the problem was pretty obvious. It's fixed for me with https://patchwork.freedesktop.org/patch/113573/. I apologize for the inconvenience.

Tested and it seems fixed over here. Closing.
