What happened?

I have a CPU running ubuntu with 2 monitors and a laptop running windows 11 in the following configuration:

| Server - Ubuntu - Screen 2 | | Server - Ubuntu - Screen 1 | | Client - Win - Screen 1 |
| 3840 x 2160 | | 2560 x 1080 | | 1920 x 1080 |
|| || |_______________________________|

This setup used to work perfectly with Ubuntu 18.04. I recently moved to Ubuntu 22.04 and this same setup is not working at all. The logs show that the client and the server are connected and there's no error. I can sometimes even copy the clipboard from one to another but the mouse doesn't move from server to client. However when I disable one of the monitors on the server and set it use only one display in the following configuration

| Server - Ubuntu - Screen 2 | | Client - Win - Screen 1 |
| 3840 x 2160 | | 1920 x 1080 |
|| ||

Then everything works perfectly.
