Running opera beta 32.0.1948.19 on Windows 10
Right now opera doesn't seem to pick up that it needs to rescale when moving between monitors with different resolution settings. I have one 4k monitor and one 1080p. Opera opens on the 4k one and looks fine. Creating a new window and dragging it to the 2nd monitor results in a 'zoomed in' interface because it's still scaled for appearing proper at 4k resolution. Would be nice to see it fixed.
