Octocam on bullseye with libcamera-still image artifacts

Support

I recently picked up an Octocam kit and it works great with MotionEyeOS.

I wanted to try the newer camera stack so I could try out HDR functionality with libcamera-still, so I installed Raspberry Pi OS Bullseye (32 bit lite). libcamera-still can take pictures but they have these strange pink circle / square artifacts / blobs at the top of the image.

If I enable the legacy camera stack on this OS with raspi-config, and use raspistill, I don’t see these artifacts.
