     event.preventDefault();
     mainWindow.hide();
});

3. Set fullscreen mode
4. Click close button

Expected Behavior

Window is hidden

Actual Behavior

Full screen gets black

Screenshots

Notes

Bug is not actual if mainWindow was cloed from normal mode (not fullscreen)

[HaNdTriX]

The same bug applies to Electron-Version 7 as well:

• electron@7.0.0-beta.3
• electron@7.0.0-beta.4
• electron@7.0.0-beta.5

@alxmiron did you found a workaround?

window.on('close', (event) => {
  if (window.isFullScreen()) {
    window.setFullScreen(false)
  }
  // The following line is being ignored :-(
  window.hide()
})

[alxmiron]

Not yet. Yes, you can exit fullscreen or exit entire app instead of hiding, but it's not an expected behavior

@HaNdTriX @alxmiron You can use setTimeout, like:

if (is.macos && mainWindow.isFullScreen()) {
  mainWindow.setFullScreen(false)
  await wait(750)
}
mainWindow.hide()

[holmberd]

@jackple instead of a timeout you can use the callback from the leave-full-screen window event.

I also encountered this problem, thanks to the leave-full-screen event mentioned by @holmberd , this is my code :

window.on('close', (event) => {
  if (window.isFullScreen()) {
    window.once('leave-full-screen', () => window.hide())

    window.setFullScreen(false)
  } else {
    window.hide()
  }
})

This issue persists. Not that the workaround is particularly difficult, but it is a bug nonetheless. Please re-open.
