Fullscreen mode not true fullscreen - windows behind NW.js still being rendered

[rogerscg]

NWJS Version : 30.4
Operating System : Windows 10 64 Bit

Expected behavior

Setting fullscreen: true uses true fullscreen, preventing windows behind the app to be rendered.

Actual behavior

When using fullscreen: true, the app behaves as borderless windowed, not true fullscreen.

How to reproduce

I'm using this package.json:

    "title": "My App",
    "frame": false,
    "width": 800,
    "height": 600,
    "icon": "assets/textures/icon.png",
    "fullscreen": true,
    "toolbar": false
  },
  "chromium-args": "--in-process-gpu --disable-transparency"

The game starts in full screen, but it's not a true fullscreen.

Would you please provide a screenshot or other things to show that it is not a true fullscreen?
I test with nwjs-sdk-v0.30.4-win, and it starts in fullscreen like the screenshot below.
And I check the fullscreen state with win.isFullscreen and check again after win.leaveFullscreen(). The result are ture and false.

@ffanny I think the reporter tries to point out that NWjs is using borderless-window fullscreen instead of native fullscreen (e.g. with full control over the brightness and resolution of the screen).

That's correct @TheRealDannyyy.

Thanks for reporting. If you mean exclusive fullscreen mode that bypasses window manager, I'm afraid that current Chromium doesn't support it. We'll support it after when Chromium does so. See also w3c/html#375

any updates? I want it to overlay overtop Minecraft Bedrock edition when it's full screened. Or any exclusive full screen app for that matter.

My app is an overlay service.

I had a weird interaction where it worked randomly for an hour or so and then stopped working.
