line of empty pixels in Photoshop

I'm getting an line of empty pixels along the right side when I create a document using a saved preset. This happens both on documents that I created on another computer using an older version of photoshop (2019) - where they appear fine - and those I created using a new preset on a new computer automatically updated to the newest version of Photoshop. If I create a new document using one of the built-in presets and then resize it to the size I want, it's fine...but annoying. 

Any idea what's going on and how to stop it?
