Expected Behavior

When a BrowserWindow is initialized with the following properties:

{
    titleBarStyle: "hidden",
    maximizable: false,
    minimizable: false,
    titleBarOverlay: true,
}

The window's controls overlay should disable (or not display) the maximize and minimize buttons.

Actual Behavior

The window still displays the maximize and minimize buttons, and the window can still be maximized or minimized using these buttons when maximizable and minimizable are set to false.

Also wanted to add, the maximize button seems to be doing nothing for me. Minimize and close works.
Tested on both Win10 and Win11, window options on creation set to: { transparent:true, frame:true, titleBarStatus: 'hidden', maximizable: true,resizable:true, titleBarOverlay: true }

I can confirm this bug also for Electron 16.
Are there any plans for delivering a fix?

[SquitchYT]

I have the same bug when setting window as transparent. But in my case, i don't set maximizable and minimizable as false

[gpetrov]

Still happening in Electron 18, very annoying bug, we just can't disable/hide the minimize or maximize buttons. This makes the WCO integration a bit useless.

@clavin any ideas?

[panther7]

Is maximizable and minimizable somewhere are documented?

[limacheb]

Still happening in Electron 19.
This makes the WCO unusable for us.
I would appreciate a statement from the electron team in respect to the timeline by when this could be fixed.
