Thumbor 不处理整个图像底部有一个灰色框

如何解决Thumbor 不处理整个图像底部有一个灰色框

最近，thumbor 处理的一些图像底部有一个灰色框。例如：

https://thumbor.dev.publicare.ch/wtI1suiCC8cqFbcJbfm1M4roXz8=/900x0/https://engine.dev.publicare.ch/cdn/storage/media/zMNiwiueR7Lnq9Jfc/original/zMNiwiueR7Lnq9Jfc.jpg

我尝试重新启动容器，清除redis-chache，更改AUTO_WEBP，获取不同尺寸的图像等。但没有任何帮助。我认为问题在于它存储原始图像的 thumbor 缓存。但我找不到清除缓存的方法。

这是我的 docker-compose 文件：
