MacOS Sierra Full-screen mode issue
I use Vivaldi snapshot 1.5.609.8 on macOS Sierra 10.12. When I opened new window in macOS Sierra's full-screen mode, two strange things happened! [b]【first case】"Original window become black!"[/b] When I opened new window in macOS Sierra's full-screen mode, new full-screen window was opened. But original window became black.

[b]【Second case】"Being piled up in one full-screen mode space!"[/b] When I opened new window in macOS Sierra's full-screen mode, new full-screen window sometimes was piled up in original full-screen mode space. like this.

[b]P.S.[/b] I think the reasons of these two cases is macOS Sierra. Because these issue was happened on Opera Stable 40, too.
I can confirm the strange space issue in the recent stable build (1.4.589.29) when opening a new private window. It seems to be already grouping the windows as tabs, which was one of Sierra's features, as pictured below…
This one shows the empty space without the menu bar…
I confirmed that second case ("Being piled up in one full-screen mode space") happened on Firefox 49.0 on macOS Sierra. So, I think the reasons of these two cases is macOS Sierra.
Incidentally, another bug like second case happen on Safari 10.0 on macOS Sierra. When I opened new window in macOS Sierra's full-screen mode, Safari opened new "tab"!
So, I think this issue connect with macOS Sierra's new feature "Tabs", too.
When I opened new "private" window in macOS Sierra's full-screen mode, Safari opened new normal private window. And when I opened new window in Desktop mode, Safari opened new normal window.
Thanks for letting us know about this issue. We're currently looking into and created the following issue: VB-21828
Check vivaldi.net we'll share its fix there.
Thank you for using Vivaldi and helping us.
I found the setting these issues doesn't happened! When I selected this option ( [Dock > Tabs setting >"Manually"] ) on macOS Sierra's System Preferences App, these issues didn't happened!
But, not perfect! When I opened a new window on macOS Sierra's Full-screen mode, New window sometimes opened on the lower half part of original window. like this.
I use Vivaldi snapshot 1.5.626.8 on macOS Sierra 10.12.
