We were able to observe this by just using either waylandsink (using dmabuf from the V4L2 rkvdec/rkvpu drivers), or even weston-simple-egl. I have not been able to do a full review of Sascha's submission, but from what I've seen of it, it should have fixed those issues. (I don't have RK3568 hardware to hand anymore.) Cheers, Daniel
