Comment (by GqU):

 The problems is also present in normal h264_cuvid decoding with -deint 2 .
 ffmpeg -c:v h264_cuvid -deint 2 -i input.mkv output.mkv
 adding "*2" fixed the problem.

 return ((av_fifo_can_read(ctx->frame_queue) + shift) >> shift)*2 +
 ctx->cuparseinfo.ulMaxDisplayDelay >= ctx->nb_surfaces;
