There is no way to know what you did from that jpeg. I have no problem splitting an imege into any number of sections; I just use menu view new guide layeout to set up the sections. Then run my Photoshop scrript to dice up the image.
Thanks for your reply. I should've worded my post better.. I didn't do anything with my file.
I'm using an external monitor (Benq PD2700U), and whenever I enlarge my Photoshop window past a certain size, the viewport breaks the image apart into quadrants, and I can't see the entire image (as in the screenshot I uploaded). It doesn't happen all the time, but has been happening enough to make me write this post to get some answers. I want to know if anyone else has experienced it.
I'm running Mac OS Big Sur 11.2.2 on a 2018 Macbook Pro - 16gb ram, and using the latest Photoshop 22.2.0.
