Confirmed.
I just upgraded to Opera 27 (direct download - not the version Opera 26 in standard Repos).
So far it looks just as I'd expect (rather spanky and shiny) - can read the url bar. It's light (rather than dark, as with Firefox/Chromium browsers) but still - good work.
Maybe some themes will darken it nicely - I'm off to play.
Welcome back, Opera - I've been away for a very long time.
