Public bug reported:

I'm using Dell XPS 13 (9350) with MIPI webcam. My laptop came
preinstalled with Ubuntu, with OEM kernel (oem-sommerville-tyrogue)
enabling MIPI camera usage. However, upon opening GNOME's Camera app,
there are graphical artefacts around the shutter button. The thumbnail
showing the last captured video also glitches (it works fine in photo
mode). "About Camera" also doesn't work, causing the app to crash and
quit.
