In some server configurations, output buffering will cause the image content to be truncated by approximately 5 rows of pixels. I can confirm that this happened with both PHP 7.4 and 8.0, using both GD and Imagick drivers. I was able to recreate the original issue by using `ob_start()` on the affected line using my local MAMP environment. Switching it to `ob_end_clean()` resolve the issue on both my development and the production machines. The solution is to just end output buffering before processing the response.

To verify, I recreated the original issue by using
ob_start()on the same line in my local MAMP environment. Output was then truncated, and my browser showed an image corrupt message. Swapping it for the correctob_end_clean()resolved the issue on both my development and the production machines.This just ensures that any automatic output buffering is turned off properly.
