Kamvas Pro 16 Causing Huge Lag When Pen Touches Screen

As in the title; it started all of a sudden last night while I was working, first registering as a dead spot. Then, the pen didn't register at all, so I unplugged my tablet and left it overnight to figure out in the morning.

Today, the cursor drifts a short distance behind my actual pen and jumps/stutters when I try to do long strokes. Sometimes, when "undo"ing strokes, what appeared to me as separate strokes are counted as all the same motion, and sometimes after a stroke has been processed the lines will be much darker and thicker than intended, as though the pen was under great pressure.

Any input I make while the pen is close enough to register is hugely delayed -- e.g. pressing ctrl+z or navigating menus with my pen will not only be slow because of the drifting cursor, but the menus themselves will take a couple of seconds to register. I think my press key buttons are also slow to register as well. If I lift my pen up and away from the screen and interact with my trackpad and/or keyboard instead, the lag disappears.

It happens in Clip Studio Paint, Rebelle, MS Paint, and even when making test selections on my naked desktop, so it doesn't seem to be specific to a program. When my pen is down, CPU use by "Huiontabletcore.exe" jumps from around 2% to 5%, but overall performance stats are normal according to Task Manager.

I've tried changing my nib, switching to a different cable (using USB-C), uninstalling my drivers, updating my drivers and restarting my computer multiple, but nothing seems to have worked. I'm using Windows 10. Anyone else have this problem and/or know how to fix it?
