LG Ultrafine 5k ghosting

I have the same problem with LG 5K 34WK95U, LG support tried to replace the matrix (display) 2 times and it did not help, next time they tried to replace the system plate of the monitor and did not help too. All were done in 2021. So there is some problem with nanoIPS technology. They offered money back, but in our country, only LG sells 5K TH3 monitors. So I will live with this monitor until Apple release a cheaper monitor than the current 6K XDR.

Does the issue occur without the external monitor connected?
