Sometimes, zooming in on the profile picture can cause it to be distorted or squashed. The profile picture may appear wider or narrower than usual. This problem often occurs when the aspect ratio is not properly adjusted. Make sure the aspect ratio is correct before uploading. Avoid enlarging or reducing the image greatly to avoid distortion.
Another common problem with zooming the profile picture is cropping, or cutting off important details. This can happen if the image is not cropped properly or the zoom function is not working properly. To avoid this problem, check the image preview carefully before uploading it. Adjust the zoom and crop so that your profile picture is fully visible and no important elements are missing.
