I’ve had this problem recently,
My Wacom Bamboo Pen & Touch tablet wouldn’t stop glitching/lagging around the screen whenever I pressed to drag… which was horrible and making it prone to useless.. and it is not my computers’ specs fault, although it does run windows /joke ..
So I tried Google! Since google always has the answer.
[UPDATED 2021-21-01] In Windows 10 they’ve kindly hidden the “Pen and Touch“-utility. In fact, I couldn’t even search for it in the Control Panel, because it just jumped to the “About System” screen.
Enter This Solution. Open a new Windows Explorer window, and type `Control Panel` like below,
Hit Enter, and the old Control Panel we know and love will appear, Choose “Hardware and Sound” or “Hardware og Lyd” if your machine is in Danish like mine 🙃
Choose the “Pen and Touch” option, now available,
And for the “Press and hold” or “Tryk og hold” go to “Settings/Indstillinger…” and disable the “Activate press and hold to right click.”
Press OK, save settings. I had to restart Paint before it picked up the change, but oh well.
Thank you Microsoft, once again, for making such a trivial exercise into something I have to write down for next time.
Best of luck.

Quick Fix: connect the tablet, open the utility “pen and touch” and disable the “press and hold to right-click”.
More details
It seems that when you press and hold the pen, it wants to help you out and make a right click. Now, if you have a pen with a couple of buttons which already has right click enabled, you might not need this, thus you can go to Start, and search for “pen and touch“, and the utility will pop up! (if you can’t find it, and you have installed the drivers, it should be under Control Panel, also called “pen and touch“). Your tablet should be connected to do this btw, I just tried finding it, and the utility was hidden from me since it was not connected… Thank you windows…
So, from here there’s something called press and hold which corresponds to a mouse right click, and if you select this, press settings, de-check the box, press ok and apply – the pen should stop lagging around when you click and drag. Wonderful.
Also, some suggested that you also disable the “flicks” – direction shortcuts, since this also causes the computer to be wondering what you might want to do every time you put the pen down, so you can also disable this if you’re not using it and want it to function even smoother.
I hope this helps someone!
