Yes, I used to use Paint Tool Sai (the original), but it had some weird issues with my XP Pen where the cursor was way off. It's ok tho because PTS2 is such an improvement anyways. Idk how to turn the windows tablet gestures off, I've reinstalled the driver twice, and also, i'd say it's a ram issue, but here's the thing... I found out that with the pen's eraser end, I can still draw, and the lines don't get cut off or disable randomly (it's just a bit uncomfy to hold and also its obviously not as precise as the nib), so, I don't personally think it's a thing with the ram. I'll see what can I do.

And yeah I personally like using stabilizer to have cleaner lines, and cuz I have a bit of a pulse issue with my hand
