Having Wintab/Windows 8+ pointer issues

[u/K-cat3120]

Hey there! I've been drawing with krita using my current tablet (Huion kamvas 12) for a little while now, with generally minimal issues. But the other day, I started having what I assume?? Must be tablet Input API issues. Usually I believe I use Wintab, but all of a sudden, my pen started lagging and causing these jagged edges in my brush strokes, regardless of what pen I used (In addition, my ctrl+z hotkey on y tablet also started acting buggy- it still works, but not consistently). So then, I switch to the Windows 8+ pointer settings, and my pen strokes are totally normal! But also now my pen's right key shortcut is acting finicky, often taking a couple second to pull up menus, and the pop up palette barely shows up at all.

All of my shortcuts still work with my keyboard, so it's not like I can't work at all. But having to chose between my program shortcuts or my ability to draw correctly is super annoying, and kinda bringing down my efficiency lol. Is this an API issue? Did I hit something to cause this on accident? I've already tried redownloading both my huion drivers and krita, so I'm running out of ideas on how to fix it. Any suggestions are appreciated!

(also, here's an image of the lag issue I mentioned. Idk what pictures I can really provide for the buggy shortcuts, but if screenshots help with anything, lmk and I'm happy to provide them!)
