I recently freshly installed Manjaro Gnome. I find that camera in Cheese is flickering and also taking a photo hangs the Application.
Also when I try to remove it, it says it has some dependency issue with gnome-control-centre.
If I run Cheese from Terminal it shows the following.
(cheese:2657): cheese-WARNING **: 17:14:05.128: Internal GStreamer error: code not implemented.

Hi I came across the same issue and cannot understand why the Official repo Cheese is not working and has flickering. However the Flatpak one is working fine. Maybe give that a try. I think it’s a bug with gnome 40 or something. I’m not sure.
There is no need to install the cheese flatpak. Either downgrading the packages below to version 0.3.25 or updating them to 0.3.27 and above should fix that problem:
