GNOME + Wayland issues

Hi guys.
I switched today from nvidia 340 drivers to Nouveau. Everything worked well, GNOME with Wayland session too. I have two monitors attached to the video card, both 1920x1080, one via DVI and one via HDMI. Usually i use onli the former, and I switch on the latter (a TV) only when I want to reproduce videos in a bigger screen. So i went on GNOME Control Center and I disable the second screen, but from that moment my (primary) screen looks awful unless in the screenshots it seems all right!

Screenshot 1 vs Real 1 (zoom details to see the difference)
Screenshot 2 vs Real 2 (zoom details to see the difference)

No way to revert the change. It start working well if I reduce the resolution (the issue appears only in 1920x1080) or if I use gnome on Xorg. The GDM login screen is also OK.
Help me please, thank you in advance.

EDIT
If i do

$ rm .config/monitors.xml

all works well until i make some changes in GNOME Control Center and the file is re-created. I post it.
