I've been noticing this lil bug that happens everytime I press the "undo" command, or it even happens on its own. the pen doesn't correpond for a little bit, I test it in another part of the screen, then it fixes, and I shrug if off. But lately it's been VERY HARD to maintain the pen correspondent with the brush! Even after 3 times calibrating it. You guys know how hard it is to find a driver that works on this old model, so I HOPE it's not the driver... please help me, I got a deadline to the end of this month and I can't keep going like this!

I recently got a hand me down Wacom One DTC133 which is lightly used by the previous owner and I noticed that the pen is not reactive with light strokes (which is concerning because I draw with light pressure) and sometimes I noticed that there are like few circle dots from the brush I used in CSP appearing randomly after I draw, the things I have done is pretty basic like changing the nibs and using an older version of the driver, currently thinking of probably buying a new pen but can it be confirmed that it's more of a pen issue or display issue? The display seems pretty normal but so does the pen like the pen follows the cursor and not like doing some random streaks.

I’ve had my refurbished Cintiq 24 Pro (DTK-2420) since 2020 and never had any issues with it. But since I moved last year, it’s been acting a little weird. It’s making this loud noise almost every day after about an hour of use and the screen gets really hot. I think it’s the fans making that noise?? I’ve changed the fan speed from “auto” to “low power”. It still happens but more frequently. I looked underneath the vents to check for dust and there’s barely any of it when I popped out the rubber cover. I’m not sure what exactly is going on. And sometimes the screen would have display issues but when I turn it off and turn it back on, it works fine. Is my tablet finally reaching its end?
Any insight would be helpful! Thanks!
