app：srcCompat在Android 6.0上显示不良

Question

请查看图片

我使用app：srcCompat将一个矢量drawable插入到ImageView中，它在Android 6.0上显示效果不错但在Android 6.0上显示不好。

这是xml布局代码：

<android.support.v7.widget.AppCompatImageView
                android:layout_width="match_parent"
                android:layout_height="136dp"
                android:layout_gravity="center_horizontal"
                android:layout_weight="0.20"
                tools:ignore="MissingPrefix"
                app:srcCompat="@drawable/iaccess_logo" />

这是可绘制的xml：

<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="768.65dp"
    android:height="317.66dp"
    android:viewportWidth="768.65"
    android:viewportHeight="317.66">
