Background panorama incompatible with Material Shell

[deadly-platypus]

Describe the Bug

The panorama photo does not display in the background. Instead, a screenshot of the non-cube workspace is displayed. I have attached a screenshot of the bug, which shows my terminal on the cube face, and the background showing the terminal as it is displayed when the cube is not being displayed.

Steps to reproduce the behavior:

1. Select a photo from polyhaven.com/hdris
2. Download the 8k tonemapped jpg
3. Set the photo as the background panorama
4. Display the cube

Log output:

Expected Behavior

The photo is displayed in the background when the cube is displayed.

System

• GNOME Shell version: GNOME Shell 42.2

Hi there, thanks for the report! On GNOME 42.1, everything is working fine for me. Did it work for you before? Could you please disable all other extensions and test it again?

[deadly-platypus]

It looks like the Material Shell extension is what is causing the issue. When that is disabled, my background photo behaves as expected.

[Schneegans]

Well, I guess this is an incompatibility of the two extensions. This has quite a low priority for me. But I'll leave this issue open in case anybody wants to fix this!

I am a software developer, and maybe I can fix it. Could you give me a place in the code to start looking?
