By trying out various snapshot kernels, I now got it nailed down to a single
major version bump:
6.13.11-1~exp1 is still good.
6.14.6-1~exp1 has the problem.
While I understand from the context you gave that might not be the
easiiest thing to make possible, but I think the most effective next
step would be now to try upstream 6.13 and upstream 6.14.6 and then
bisect.
There's probably a subfolder I can restrict this to? Which folder has the
webcam drivers? (And maybe the v4l infrastructure.)
I would not recommend that. The problem might also be triggered by a
change to your USB controller's driver or something in the graphics
stack.
Fair, I didn't realize how entangled the webcam stack is these days.
Thanks for forwarding this to a kernel maintainer!
Kind regards,
Ralf
