Xorg.log
With xf86-video-amdgpu git I cannot start the sddm login manager anymore.
Reverting the driver back to 1.0.1 fixes the problem.
Bisecting shows the following commit as the guilty party:

glamor: Avoid generating GEM flink names for BOs shared via DRI3 (v2)
We can't create our own struct amdgpu_buffer representation in this case
because destroying that would make the GEM handle inaccessible to glamor
as well. So just get the handle directly via dma-buf.
(ported from radeon commit 391900a670addec39515f924265bfa9f8bfa9ec0,
extended to cache BO handles in the private for non-DRI3 pixmaps as
well)
v2: Swap whole pixmap privates instead of just BOs in
amdgpu_dri2_exchange_buffers to avoid invalidating cached BO handles
