--- Comment #13 from Carlo Caione carlo@caione.org ---
I just tried the HEAD of xf86-video-amdgpu and now instead of having a black screen I have the image corruption as shown in the picture.
Just FYI this is due to commit b09fde0d81 ("Use reference counting for tracking KMS framebuffer lifetimes").
