Comment (by oromit):

 Yes, this is known.
 We are pretty sure that the bug in question is on Nvidias end though.
 If you feed cuda frames to nvenc by using hwupload_cuda, bframes work as
 expected, so this can't be a bug in the ffmpeg CUDA frame input code in
 nvenc, leaving only a weird driver bug.
