【报Bug】uni-swiper-dot 与 swiper 做轮播, 从后台切换到前台 出现卡顿

示例代码：

<template> <uni-swiper-dot class="page-11" :info="list" field="content" :current="current"> <swiper class="box-swiper" @change="change" :autoplay="true" :interval="interval" :duration="duration" current="current"> <swiper-item v-for="(item ,index) in list" :key="index" @click="open(item)">
<view class="swiper-item">
<cc-image group="home-ad" :src="item.image" mode="widthFix"></cc-image>
</view>
</swiper-item>
</swiper>
</uni-swiper-dot>
</template>

<script>
import ajax from "@/utils/ajax.js";
import jut from "@/utils/jut.js";

export default {  
    name: "home-main-carousel",  
    data() {  
        return {  
            interval: 3000,  
            duration: 500,  
            list: [],  
            current: 0  
        };  
    },  
    mounted() {  
        this.load();  
    },  
    methods: {  
        load() {  
            ajax('/ad/carousel/of-home').cache().get(list => this.list = list);  
        },  
        change(e) {  
            this.current = e.detail.current;  
        },  
        open(item) {  
            let data = {};  
            if (item.data) {  
                data = JSON.parse(item.data)  
            } else {  
                return;  
            }  
            let url;  
            let param;  
            if (data.open.indexOf("?") == -1) {  
                url = data.open;  
                param = {};  
            } else {  
                param = jut.search(data.open);  
                url = data.open.substr(0, data.open.indexOf("?"));  
            }  
            this.$Router.push({  
                path: url,  
                query: param,  
            });  
        }  
    }  
}  

</script>

<style lang="scss">
.page-11,
.box-swiper,
.swiper-item{
width: 100vw;
height: 318.75rpx;
}
</style>

操作步骤：

打开后运行一会切换到后台, 然后过一会再次切换回来 就出现这样的问题,
真机运行

预期结果：

无卡顿

实际结果：

卡卡卡卡
