Cursor is blocking automation?

Here's a weird one. I just set up a new additional monitor to work with my PC, and since then, it appears like my cursor size has changed. In the new monitor, the cursor while it's in the Editor suddenly grows in size, to the point where I can't see the automation numbers when I try to change them. I'm baffled. Doubly strangely, now when I'm trying to edit on my laptop screen, the little square under the cursor when I'm trying to adjust automation is also blocking the numbers. What happened? How do I fix this?
