moving calculator app up/down introduces artifacts

OS: Arch Linux

Bug occurs since kernel 6.5.3-arch1-1, last known good kernel is 6.5.2.arch1-1.

Two monitors are attached:
- secondary @60Hz via DVI
- primary @143.91Hz (freesync capable) via DisplayPort

Kernel boot options:
- amdgpu.ppfeaturemask=0xffffffff

Xorg options:
- VariableRefresh true
- AsyncFlipSecondaries true

Artifacts occur only on primary monitor on every GUI element that gets redrawn.
Bug is fixed once I enable TearFree option on primary monitor (xrandr --output
DisplayPort-2 --set TearFree on).
Bug reoccurs when I disable TearFree option.

OBS could not capture the artifacts so I had to take a video with my phone, see
attachment.
