Comment # 6 on bug 103317 from Torsten Kessler

The new display engine (amdgpu.dc=1) definitely helps. It nearly eliminates the
flickering during videos or browsing. It has no effect on 3D applications, for
example 0ad.
There seems to be a bug in the amd-staging-drm-next branch. Rotating the screen
with xrandr results in a blackscreen. But this will be a different bug report.
That's why I using the kernel from the amd-staging-4.13 branch with
amdgpu.dc=1.
