How to have consistent cursor size on HiDPI?

So, I'm on a HiDPI machine (XPS 9370) and using the Adwaita cursor; this is on a fresh install of Antergos w/ i3 for context. I've been playing around with some settings for adapting to HiDPI, but I realized that my cursor changes size depending on what application it is hovering on. Whereas when not hovering over any application or hovering over a few, it may be sized appropriately for the display, but, say when hovering over termite or Firefox, it will decrease to a fraction of the size and become barely visible. How do I make the cursor size consistent across the entire system? Xcursor.size does not seem to affect the cursor sizes in the programs I listed.
