Bug#1055810: cheese: Cheese does not give video output, camera led blinks

[Fekete Tamás]

Package: cheese
Version: 43.0-1
Severity: important

When I open cheese, all camera leds start blinking. No button is responsive
within the app, only closing the application is possible.

For the possible problem: I have Lenovo Thinkpad T480 which has two built-in
camera. One in Infra, one is normal:

I think cheese is unable to decide which camera to use. I think this can be the
problem because all cameras led is blinking.
I checked the normal camera in browser on an online platform. It works so the
problem is with the application.

One more error in journalctl which can be related to this problem:

cheese[29602]: Unable to create dummy onscreen: No foreign surface, and
wl_shell unsupported by the compositor
