iOS 上的 Bug Carousel Bootstrap 5.3

Question

我有一个 bootstrap 5.3 的旋转木马，我使用类“round-4”来圆化旋转木马的角落。在每台电脑和手机上，旋转木马都是完美的，但在 iOS 上，圆角被打破了。当旋转木马滑动时，角落变得尖锐，然后返回圆形 这是我的旋转木马：

<div id="slideShow" class="carousel slide draggable bg-dark rounded-4" data-bs-ride="carousel" data-bs-pause="false">
    <div class="carousel-indicators">
        <button type="button" data-bs-target="#slideShow" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
        <button type="button" data-bs-target="#slideShow" data-bs-slide-to="1" aria-label="Slide 2"></button>
        <button type="button" data-bs-target="#slideShow" data-bs-slide-to="2" aria-label="Slide 3"></button>
    </div>
    <div class="carousel-inner rounded-4">
        <div class="carousel-item active">
            <img src="img/IMG_1.jpg" class="d-block w-100" alt="...">
        </div>
        <div class="carousel-item">
            <img src="img/IMG_2.jpg" class="d-block w-100" alt="...">
        </div>
        <div class="carousel-item">
            <img src="img/IMG_3.jpg" class="d-block w-100" alt="...">
        </div>
    </div>
    <button class="carousel-control-prev" type="button" data-bs-target="#slideShow" data-bs-slide="prev">
        <span class="carousel-control-prev-icon" aria-hidden="true"></span>
        <span class="visually-hidden">Previous</span>
    </button>
    <button class="carousel-control-next" type="button" data-bs-target="#slideShow" data-bs-slide="next">
        <span class="carousel-control-next-icon" aria-hidden="true"></span>
        <span class="visually-hidden">Next</span>
    </button>
</div>

我不知道该尝试什么，因为问题只出现在 iOS 上
