IPU6 Camera used to work in F41. In F42 camera feed is upside down

I have a Lenovo thinkbook-13x-gen4 with an Intel IPU6 camera. Everything used to work perfectly with the rpmfusion drivers (see discussion here), but ever since updating to F42 the camera feed is now upside down. Any solution?

I can confirm the issue, but for me this is a huge achievement: the cam was not working before, but F42 made it happen!
Unfortunately video conference participants are easily distracted by the upside down view…

here is a qcam stdout that might indicate something…

Let me add that in my case the camera works as expected with the 6.14.5 kernel, but not with the most recent one (currently 6.14.6).

I had no problems with F41 with the camera with the rpmfusion kernels.

The FOSS drivers instead do not work at all at the moment (I haven’t tested it now, but they used to cause kernel panics).

Reddit - The heart of the internet

The article above proposes to use gnome-video-effect to flip the image back.

This might be a Workaround till there is a fix?

Update: in my case the issue does not arise with Kernel 6.14.5, but it does arise with 6.14.6 and 6.14.8.

Generally speaking, it would be good to have some up-to-date guidelines about what to do with IPU6 cameras. Especially since new Intel laptops all ship with it now.
