nw2: Initial window size is wrong

[Luzzifus]

NWJS Version : 0.42.5
Operating System : Win10 (1903)

Expected behavior

Calling nw.Window.open() with the window flags "width" and "height" should open a window with the given size.

Actual behavior

The actual size of the opened window is smaller. Adding a .resizeTo() in the callback of nw.Window.open() doesn't help. Calling .resizeTo() a bit later sets the correct size.

How to reproduce

Only happens in NW2 mode, works as expected with "chromium-args": "--disable-features=nw2".

This yields a window which is smaller than 250x100 (in my case 234x92):

let windowOptions = {
  show: true,
  title: 'test',
  width: 250,
  height: 100,
  position: 'center',
  frame: false,
  transparent: true,
  show_in_taskbar: false
};

nw.Window.open('html/widget.html', windowOptions);

This still results in the smaller window:

let cb = win => win.resizeTo(250, 100);
nw.Window.open('html/widget.html', windowOptions, cb);

This result in the correctly sized window:

let cb = win => setTimeout(() => win.resizeTo(250, 100), 100);
nw.Window.open('html/widget.html', windowOptions, cb);

I recently clarified the setting of inner/outer dimension if the window:

So the behaviour would be different with NW1.

This scenario is working as expected for me and it's covered in the tests: https://github.com/nwjs/nw.js/tree/nw43/test/sanity/window-resizeto

close for now.

@rogerwang I checked again with 0.43.2 and a minimal code example. The whole behaviour in this issue seems to be related to the transparent window option misbehaviour. It works for non-transparent windows, but if I try to make the window transparent, I get the non-transparent background window as described/shown in #7221 and the actual content element is too small.

So yes, it works for non-transparent windows.
