The patch does resolve the issue! There was a problem with my particular setup caused by the fact that my greeter didn't have the VRR feature enabled, which made the desktop environment take longer to start and the following error messages were printed to the kernel log: amdgpu 0000:2d:00.0: amdgpu: SMU: I'm not done with your previous command: = SMN_C2PMSG_66:0x00000028 SMN_C2PMSG_82:0x00000000 amdgpu 0000:2d:00.0: amdgpu: Failed to enable gfxoff! amdgpu 0000:2d:00.0: amdgpu: SMU: I'm not done with your previous command: = SMN_C2PMSG_66:0x00000028 SMN_C2PMSG_82:0x00000000 amdgpu 0000:2d:00.0: amdgpu: Failed to set workload mask 0x00000001 amdgpu 0000:2d:00.0: amdgpu: (-62) failed to disable fullscreen 3D power pr= ofile mode These errors do not appear without the patch, nor do they appear with the patch if the greeter and the DE have VRR enabled (in my case, GDM and GNOME Shell respectively). I have not tested the case of greeter having VRR enabled, but disabled in DE.
