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. > > And what architecture and platform are you on?=20 >=20 > A x86_64 laptop (with Core i5-11300H CPU). >=20 --=20 Xi Ruoyao School of Aerospace Science and Technology, Xidian University
