• Bug Report
• Feature Request
• Successfully reproduced against the latest version of NW.js?

Current/Missing Behavior

After using nw.Window.get().toggleFullscreen() to enter and exit fullscreen, the window is behaving unexpectedly. There are 2 symptoms:

1. event document.onkeydown stops being triggered after any key is pressed. This can be worked around by pressing tab key and then the event starts being triggered correctly again. The issue can be also verified by pressing any other keys than tab, e.g. arrows or letters (even 'f' stops working) - the application will issue 'error' sound like as if you reach end of some input form and try to type further.

2. black line appears on the bottom of the screen after exiting fullscreen. see attachments

Symptom 1) happens 9 out of 10 times the application is launched.
Symptom 2) happens completely randomly, i.e. 5 times app is launched, no black stripe. 5 times launched later on, the symptom is there.

After exiting fullscreen mode:

Expected/Proposed Behavior

1. Same behavior all the time
2. Fullscreen toggle should have no effect on onkeydown event.
3. Black stripe should not appear after exiting fullscreen.

[rribou]

I take the opportunity to say that "fullscreen" attribute in package.json doesn't make the app go in fullscreen since 0.60.0, 0.59.1 was ok. Tested with Ubuntu 22.04 and 22.10.

I just want to bump this up and confirm that it is still present in v0.77.0 on macOS.
