Window Management API not fully working on Opera GX
-

Hello,
I noticed that Opera GX already supports the window.getScreenDetails() API and correctly lists available displays and dimensions. However, when trying to open a new window on a specific screen using the left / top coordinates, the browser ignores those placement parameters.
So while sizing (width/height) works, positioning across monitors does not. This makes the API incomplete, since the main purpose of multi-screen management is to let apps choose which screen a window should appear on.
Could you clarify whether this is a known limitation in Opera GX’s implementation, or if there is a flag/permission needed to enable full screen placement (similar to Chrome’s window-management permission)?
Thank you.

Chrome’s window-management permission
Opera has that too at the URL
opera://settings/content/windowManagement. -

Do you have a test case?

@burnout426 The MDN demo (see below) is enough to reproduce the problem. If you try to open a popup on a secondary screen, Opera doesn’t respect the left/top coordinates — the window always ends up on the primary display. The dimensions (width/height) are applied correctly, so it looks like the API is partially implemented, but the multi-screen placement part just isn’t supported in Opera right now.

@andremartinsc Okay. I can confirm the issue in Opera GX 121.0.5600.81 64-bit based on Chromium 137 on Windows 11 23H2. But, it works fine in Opera One 122.0.5643.24 64-bit based on Chromium 138.
Primary Screen: 1366 x 768
Secondary Screen: 1920 x 1080
Multi-monitor mode: ExtendIn Opera GX, on screen 0, I hover the "Popup" button and choose screen 1. The window opens on screen 0 instead. In Opera One, it opens on screen 1.
In Opera GX, on screen 0, I set "left" to 1500, and click the "window" button and it opens on screen 0. In Opera One, it opens on screen 1 because 1500 is greater than the width of screen 0.

@burnout426 Thanks a lot for confirming and testing across both versions. Since it works fine in Opera One but not in GX, it does look like a GX-specific behavior (is this a bug or on purpose?).
I filed a bug report with the Opera GX team, but is there something else you’d recommend me doing?

@andremartinsc I’m pretty sure it’s not intentional and I am going to guess it’ll be fixed automatically when GX moves to 138. So, we probably just have to wait. However, what’s the number for the bug you filed?

@burnout426 I am not sure where I can find that information. I just filled the form.

@andremartinsc It usually shows the number after you file and I think you get an email too. Things could have changed though. No worries.

@burnout426 Found a JIRA link on the email I got.

Is filing the bug enough or should I do anything else other than waiting?
