Bug Description
uvcvideo: Found UVC 1.00 device Integrated Webcam (0bda:5716) from Dell XPS 12 laptop (9Q33 version) does not work properly for several versions of the kernel now.
guvcview nor cheese both show the issue, so it's the uvcvideo driver. Starting at 640x480 and higher resolutions, parts of lower half of video flickers / don't show image.
Error messages:
V4L2_CORE: (jpeg decoder) error while decoding frame
V4L2_CORE: (jpeg decoder) Ignoring empty buffer
V4L2_CORE: Error - Couldn't decode frame
VLC seems to use another driver AND DOES NOT SHOW issue.
