请教一下学习 Quasar 框架时遇到的两个诡异问题

最近在看 Quasar 框架的文档，边看边用它写了一个只有登陆界面的 demo，但是写完浏览器调试时遇到了一些奇怪的问题。.vue 文件代码如下：

<template>
    <q-layout view="hHh lpr lFr">
        <q-layout-header>
            <q-toolbar>
                <q-btn flat dense round icon="menu" @click.native="checkStatus()"/>
                <q-toolbar-title>登录</q-toolbar-title>
            </q-toolbar>
        </q-layout-header>
        <q-layout-drawer side="left" content-class="bg-grey-3" :content-style="{padding: '3px'}"
                         v-model="leftDrawerStatus">
            <q-list separator>
                <q-list-header>当前用户名</q-list-header>
                <q-item>
                    <q-item-side>
                        <q-icon name="school"/>
                    </q-item-side>
                    <q-item-main>
                        {{currentUserName}}
                    </q-item-main>
                </q-item>
            </q-list>
        </q-layout-drawer>
        <q-page-container>
            <q-page padding class="row justify-center">
                <q-field label="登录以获取信息" :error="loginHasError" orientation="vertical">
                    <q-input type="text" clearable autofocus suffix="@gmail.com" v-model="currentUserName"
                             stack-label="用户名"/>
                    <q-input v-model="password" type="password" stack-label="密码"/>
                    <div class="row justify-center">
                        <q-btn label="登录" icon="info" color="secondary" outline size="md"
                               @click="getInfo(currentUserName,password)" class="q-my-md"/>
                    </div>
                </q-field>
                <q-page-sticky position="bottom-right" :offset="[20,20]">
                    <q-fab color="primary" direction="up" icon="add" active-icon="close" persistent>
                        <q-fab-action

                        />
                        <q-fab-action
                                color="secondary"
                                @click="getInfo(currentUserName,password)"
                                icon="cached"
                        />
                    </q-fab>
                </q-page-sticky>

问题主要有两个：

1. <q-input>组件在 chrome 上没有 value 时会显示一个奇怪的竖线（见图 1 ）
2. <q-fab>弹出式按钮的图标显示位置有问题（见图 2 ）

图 2

问题 1 我验证过是 chrome 的问题，因为用 edge 浏览时不会出现这样的问题。我所使用的 chrome 版本为版本 72.0.3626.14 （正式版本） dev （ 64 位）。

问题 2 更加奇怪，在使用本地测试服务器npm run-script serve时图标定位异常，但在我运行npm run-script build并将编译好的文件上传到自己的服务器后再浏览就能正常显示图标。

远程服务器环境为：

nginx version: nginx/1.15.7
built by gcc 6.4.0 (Alpine 6.4.0) 
built with OpenSSL 1.1.1a  20 Nov 2018
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-cc-opt=-static --with-ld-opt=-static --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_sub_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --with-openssl=../openssl-${OPENSSL_VER} --with-pcre=../pcre-${PCRE_VER} --with-pcre-jit --with-zlib=../zlib-${ZLIB_VER}

nginx 配置如下：

    listen               443 ssl http2 reuseport fastopen=3;
    root /home/wwwroot/hexo;

    ssl_prefer_server_ciphers  on;

    ssl_session_timeout        1d;
    ssl_session_tickets        on;
    ssl_stapling               on;
    ssl_stapling_verify        on;
    resolver                   8.8.8.8 8.8.4.4 valid=300s;
    resolver_timeout           10s;
    add_header    Strict-Transport-Security 'max-age=31536000; includeSubDomains; preload';
    index index.html;
    location / {
        expires 120s;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
    expires 30d;
    access_log off;
    }
    location ~ .*\.(js|css)?$ {
    expires 7d;
    access_log off;
    }
}

请问可能是哪些方面的问题呢？问题 1 我觉得可能是 Quasar 本身的问题，问题 2 可能跟 chrome 处理本地页面中 webfont 的方式有关？谢谢！
