So recently I had to wipe my computer, and when I reinstalled photoshop, the transparent background now scales when I zoom in, before I had to reinstall though, when I zoomed in all the way the grid would look like it was getting bigger (cause that's what happens when you zoom in) now it looks like it gets smaller. Is there a way to change this?
Yes, you can make a grid size smaller as per your requirement in Photoshop CC.
Refer the document: DesignEasy: How To Customize Transparency Grid Settings in Photoshop CC
I do know how to do that, the issue is, when I zoom in the transparent grid changes size as I zoom in, whereas before it didn't do that. I was looking to see if there was a way to change that.
Please let us know the Photoshop version you are using now?
