Solution for Problem 1:

White border issue

After creating a plugin to convert the string value to an integer (which properly casts to a boolean), the image frame is not added. For details see this https://github.com/magento/magento2/issues/4622

public function beforeSetKeepFrame($image, $keep)
{
    if (is_string($keep)) {
        $keep = (strtolower($keep) === 'true') ? 1 : 0;
    }
    return [$keep];
}

For Resize issue:

In etc/view.xml of your current theme, you can update product image size.Make sure you resize with the expect ratio.Use additional tag <frame> to prevent white borders on image. Example Code:

<image id="product_page_main_image" type="small_image">
    <width>460</width>
    <height>460</height>
    <aspect_ratio>true</aspect_ratio>
    <frame>false</frame>
</image>

Check all other tags, not just a tag with the id product_page_main_image check others too.

Solution for Problem 2:

Go to Stores > Settings > Configuration > Customers > Reward Points

You may disable the reward functionality do whatever configuration you want to do like display on store front, reward point expiry calculation etc.

I hope this will help
