@jadanp said in Opera window doesn't fully go full screen.:
When I went on full screen, it didn't fully go full screen. Can someone help me on this?
It would be useful to know which version of MacOS you are using, which version of Opera, and how are you are invoking Full Screen … also, what you mean exactly by "Full Screen".
I'm on MacOS 10.14.6, Opera Stable version 63.0.3368.75, and have no trouble going Full Screen with tabs and sidebar using the green "traffic light" or Ctrl-Cmd-F, and Full Screen without tabs or sidebar using Shift-Cmd-F. To have the old-fashioned Full-Screen with menu-bar, Opt-Green-Traffic-Light works as expected.
