Starting with the broken 3.0.27-2build2 in -release, running
gst-launch-1.0 videotestsrc ! jpegenc ! jpegdec ! clutterautovideosink
shows a grey picture with vertical bars. Opening cheese, we see the same
vertical bars, poor video performance and purple lines.
Same problem here with a Logitech C505 on Ubuntu 22.04.

I built the patch Jan provided into a test package, available in the

Jan also added a testcase to the upstream bug, that calls clutter-gst
directly and does not require cheese:
$ gst-launch-1.0 videotestsrc ! jpegenc ! jpegdec ! clutterautovideosink

3.0.27-2build2, showing distorted picture.

I added a fix for this to Arch's `clutter-gst` (bug link

https://github.com/archlinux/svntogit-packages/blob/packages/clutter-

Hi Jack,
I booted a Fedora 36 Beta live image like you suggested, and cheese
works fine there on my machine.
Their cheese includes the above patch. I had a look around, it has a
5.17 kernel, and gstreamer 1.20.
Ubuntu has gstreamer 1.20.1, and when I booted my machine into a 5.17
kernel, I

Matthew, do you see the same corruption if you boot the same machine
with the Logitech C270 camera under a Fedora 36 Beta live image? It
would be interesting to know if their Fedora cheese 41.1 package doesn't
show the same artifact like it doesn't on my hardware.

It is very odd that Fedora 36 beta also uses a build of cheese 41.1 with
minimal patching and the apparently the same optimizations yet it
doesn't exhibit this artifact.

Hi Jack,
Thanks for reporting. I have a Logitech C270 camera, and I am also
affected.
Attached is what I see, I get green and purple bars, and overall
terrible performance.
I am on Jammy 5.15.0-25-generic, Wayland session, gnome 42, cheese
41.1-1build1.
I will start investigating.
Thanks,
