And I just borrowed a different camera:

Bus 003 Device 010: ID 1bcf:2283 Sunplus Innovation Technology Inc. FULL HD webcam

It suffers the same issue so it's unlikely to be related to a specific
camera model. This camera is also driven by uvcvideo.

v4l2gl from v4l-utils-1.28.1 suffers the issue either, so it's unlikely
to be related to a specific userspace v4l2 program too.
