Has anyone experienced this?

This is truly bizarre.  I created a action to crop a bunch of images.  The action only has 2 parts.

1. Select Subject
2. Image/Crop

I used Automate/Batch to run it on a folder with 48 small clothing images that I downloaded from a site that sells blank garments.  Here’s the crazy part.  As I watched the screen run the action, a garment would pop up, momentarily process, and the lights in my room flickered 3 or 4 times, on each garment!  LOL  There were 48 images, so I had plenty of time to make sure that I’m not imagining it.  48 times my ceiling light flickered, perfectly timed to each imaged just before it closed the image.  The image would open, process, lights flicker, then image closed.  So what does this mean?  Does this mean that Photoshop actually caused an energy surge to do each of these little images.  Each image sizes averaged 500KB.  I’ve been a Photoshop user for several decades and this is the most bizarre thing I’ve ever seen.

I’m using Photoshop 27.8
