** Description changed: Impact ====== The cheese app is unusable with color bands showing in the main view. + This bug doesn't affect all webcams. It's unknown what percentage of + webcams are affected. + Test Case ======== + On a system that experiences this bug: Install the update Run the cheese app Verify that the main view shows what your webcam can see normally. Click the camera button in the bottom toolbar area. Check if the photo looks normal. You can find it in ~/Pictures/Webcam What Could Go Wrong =================== Only 4 apps in Ubuntu use clutter-gst: empathy, cheese, lyricue, pinpoint clutter-gst has been archived by GNOME. (It's recommended for apps to use GTK4 instead of GTK3 + Clutter). That means it's not possible for this patch to be accepted upstream. Instead, distros like Arch Linux are applying this patch. This patch removes 2 renderers that don't work (RGBx and BGRx) but still keeps ones that do work: RGBA and BRGA. Original Bug Report =================== The cheese application produces a corrupted display under Ubuntu 22.04 with a Logitech C525 webcam. When started from the command line, cheese produces repeated warnings of the form... (cheese:4175): cheese-WARNING **: 05:15:48.706: A lot of buffers are being dropped.: ../libs/gst/base/gstbasesink.c(3143): gst_base_sink_is_too_late (): /GstCameraBin:camerabin/GstViewfinderBin:vf-bin/ClutterGstVideoSink:cluttergstvideosink0: There may be a timestamping problem, or this computer is too slow. Adding /etc/modprobe.d/uvcvideo.conf with 'options uvcvideo nodrop=1' doesn't solve the problem. This issue is not seen in either Ubuntu 21.10 or under Fedora-Workstation- Live-x86_64-36_Beta-1.4. The problem in Ubuntu 22.04 occurs under both Wayland and X11 displays with the Nvidia drivers.
