I don't know how to properly term this, so please bear with me!
I just went from PS CC 2014 to 2018 last week and there is one feature which is driving me crazy: I like to move around the image or canvas I am working on in my working space quite a lot in order to focus on certain areas. Let's say I've moved it over to the left (I have actions, curves, history, etc. open on the right, so usually I am moving my canvas to the left a bit in order to see things clearly during certain procedures), and I then select something on the image. What used to happen was nothing; I would simply continue doing what I needed to do and the image/canvas would stay in place. NOW, when I do this, the canvas suddenly will snap back into default position and I can't stay where I wanted to. It's incredibly annoying! Is it possible to disable this feature?
Thanks ahead of time!
I don't think it's a feature. Your description sounds like a bug that was occurring in earlier versions of CC2018 but was supposed to have been patched. Check out the following discussion thread to see if it seems like what's going on for you: Photoshop 2018 Screen Snapping Issue. If so, make sure you're fully updated to the latest version of CC2018. If that doesn't resolve the issue, review the other solutions offered.
If that thread doesn't sound like what's happening for you or if you are still experiencing problems after running through the possibilities, let us know in a reply to this discussion.
