I’m running Fedora on a Dell XPS 14 9440, which has an Intel ipu6 camera with ov02c10 sensor.
Since I’ve upgraded to Fedora 43 the video stream from camera, as seen in qcam or in a browser using Pipewire starts by fast blinking for about half a minute every time I connect to the camera. On occasionally pipwire will crash as well with the follwing core dump shown in journalctl:
Process 149311 (soft_ipa_proxy) of user 1000 dumped core.

Anybody else seeing the same behavior?
