[5.5.2] Canvas UI on Display 2 disfunctions

Hi,
I have screen space UI system which is working fine on display1 but I need to move is to the 2nd one.
When I do so, I can’t click any button anymore in the game view.
It’s kind of working in the build, but there’s a Y offset (~50 pixels) between what’s raycasted and the mouse pointer.

Has someone faced that issue?
Thanks

Yes a lot of people experience this issue. I’ve tried to get feedback but haven’t head back in a while.
