<pre>I just tried to use a Wayland session with KDE Plasma 5.13.2 (Debian testing)
and it's segfaulting right after login and falling back to sddm.
That's what I see in dmesg:
[ 176.359816] [drm:generic_reg_wait [amdgpu]] *ERROR* REG_WAIT timeout 10us *
3000 tries - dce110_stream_encoder_dp_blank line:956
[ 176.814144] QThread[2620]: segfault at f ip 00007f30f30b0e60 sp
00007f30e506e4f0 error 4 in libwayland-client.so.0.3.0[7f30f30a9000+d000]
Not sure whether it's amdgpu problem of something with KWin.
GPU: AMD Vega 56, connected over DisplayPort.
OpenGL renderer string: Radeon RX Vega (VEGA10, DRM 3.25.0, 4.17.0-1-amd64,
LLVM 6.0.1)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.1.3
