I've noticed this sort of thing since cutting over to the UI – can't get to certain areas of the pop up windows without making adjustments to my browser resolution. In the example screenshot, browser resolution needed to be adjusted to 90% to view the "save" button when adding a new image to my template.

Also drop downs dont display properly (such as, when choosing a data field or operator value in Query Builder) when using a second monitor. I have to move the pop up modal to my "primary" monitor on my laptop to view them, or, adjust the browser resolution until they display correctly, or the modal pops up on a screen other than the one I'm using, etc.
