New Incognito Window

[corrisoft-mikeg]

What Happened?

What Happened?

When opening a new Google Chrome Incognito window using the
right-click action on the elementary Dock, the new window opens
with incorrect geometry.

If the existing normal Chrome window is not maximized, the new
Incognito window appears vertically maximized but retains roughly
the width/position of the existing Chrome window.

This only happens when launching the Incognito window from the Dock.

Steps to Reproduce

1. Open Google Chrome.
2. Resize the Chrome window so that it is not maximized.
3. Right-click the Google Chrome icon in the Dock.
4. Select "New Incognito Window".

Result

The new Incognito window does not occupy the full maximized area.
Its horizontal dimensions appear related to the existing Chrome
window.

Expected Result

The Incognito window should open with normal/maximized geometry.

Additional Testing

Chrome is installed as a Flatpak:

com.google.Chrome

Running this manually works correctly:

flatpak run com.google.Chrome --incognito

The exact command from the Flatpak .desktop action also works
correctly when executed manually:

/usr/bin/flatpak run --branch=stable --arch=x86_64 \
  --command=/app/bin/chrome \
  com.google.Chrome --incognito

The issue only occurs when selecting:

Dock → right-click Google Chrome → New Incognito Window

Workaround

If I maximize the existing Chrome window first, then select
"New Incognito Window" from the Dock, the Incognito window opens
correctly.

I can then restore the original Chrome window to its previous size.

Environment

elementary OS: 8.1
Session: X11

io.elementary.dock:
8.3.3+r868+pkg21~ubuntu8.1

gala:
8.6.1+r3147+pkg134~ubuntu8.1

Google Chrome:
153.0.8010.36
Flatpak: com.google.Chrome

Steps to Reproduce

1. Open Google Chrome from the elementary Dock.
2. Resize the existing Chrome window so that it is not maximized.
3. Right-click the Google Chrome icon in the Dock.
4. Select "New Incognito Window" and maximize if not already maximized.
5. Observe that the Incognito window opens with incorrect geometry: it appears maximized vertically, but its width/position is based on the existing non-maximized Chrome window instead of filling the available screen.

Expected Behavior

The Incognito window should open using the normal maximized window geometry and fill the available desktop area.
