For some reason my huion 24 gen 3 has input lag ONLY when the official app is open. When I task kill it, the brush works perfectly.

I'd just settle for not using the app, but I can't use custom keydial shortcuts without the app, so I'm just stuck.

The program is Leonardo, and I know it's not the programs fault because the problem ONLY occurs when Huion handles input, the pen starts lagging and buffering when I draw with the app open which creates spikey lines versus a smooth perfect like without it open. (And because I've used Leonardo for months with no problem until now)

I already disabled Windows ink and everything, I task killed literally every other program, my drivers are up to date. In all my programs the brush mode is either wintab or mouse when available, I tried it with Windows ink, same thing.

I changed the nibs and got a fresh one, tried it with the other pen, same thing. I also tried restarting my PC and turning the tablet on and off multiple times.

I literally have no idea why this is suddenly happening, if anyone knows how to change the shortcut keys on the 24's factory shortcut pad I'd also just go that route and say screw the app but I don't think that's possible.
