If you know someone with a Cintiq around you, maybe you can ask to test his/her tablet on your computer?
Or maybe it’s just the pen and then, if you can try another Cintiq pen on your tablet, if everything is fine buying a new pen only?
Is your tablet is still under warranty?

I don’t know anyone with a Cintiq around here. Even less a Linux user. I’m not getting the jagged lines in Windows btw, so I’m kind of loath to call this a hardware problem.
I haven’t tried with a standard Wacom pen, since I really want the rotation feature only the Art Pen seems to provide, and don’t have other types of pen around. I doubt a new Art Pen would help since I have tested two already.
I guess I need to try to fix the splotches I get at the start of the stroke in Windows instead of trying to figure out how to get this working in Linux for now. shudder. But I haven’t managed to do that, ever, and it’s been a few years since that problem came up.
Maybe send in a bug report to the Linuxwacom project?
I probably should. But I’m not sure whether to report it as a kernel driver bug, xorg driver bug or what… Also I’m getting some USB oddities in Linux, odd error messages etc, I need to find out what that’s about, too.
Anyway that seems like it’ll take a while to get me painting again. I’ll try to see if I can get Windows + Art Pen to like themselves again.
I don’t know if it makes any difference, but here’s the output from a Cintiq:

Thanks, @Bleke . It looks like your Cintiq is also sending events without pressure data at times. Maybe that’s not the cause of my issue, then.
I assume you don’t have this kind of heavily stepped pressure issue, either:
I went and plotted the pressure vs time for that stroke above and got this:
I’m also getting some oddities with input, my keyboard seems to be dropping some keystrokes as I type this etc. Maybe related, maybe not, this is a new motherboard and this problem first surfaced with my old one!
There might be small issues with the pressure, but I haven’t noticed them so no problem for me. 
It ought to be you doing the stroke tests on my tablet. I’m pretty sure we push down and let off at differently. But your stroke does seem quite jagged even on the long taper.
edit:
My graph looks worse than yours.
How do you do to find the device adress to --grab with evtest? I have the Intuos4XL connected, but also the XPpen24Pro; I’m really also curious to understand what’s going on. (and it is really weird xsetwacom can’t make significant change for the Suppress and RawSample.)
@deevad if you just run ‘sudo evtest’ , it should enumerate the devices available.
@bleke I think my graph looks “better” because there are fewer datapoints. And that is the problem, presumably. Or maybe it’s not…
I don’t quite understand how to read that time. The number before the decimal is seconds? If so I have about 17 readings every tenth of a second.
@Deevad Here’s my command to extract the correct lines:
sudo evtest --grab /dev/input/event21 EV_KEY 24|grep PRESSURE >pressure.txt
event21 is “Wacom ISDv5 325 Pen” on my computer and “EV_KEY 24” is “ABS_PRESSURE”
Thanks for the method! Ok, here a sample of a pen gesture with the Wacom Intuos4XL:

Thanks for the interest, all! I got in touch with a linuxwacom dev on Reddit, we’ll see if that leads anywhere. They said some pens, like the Art Pen I use, output so much data that some sensors do not get updated every report. So that’s expected, but the result isn’t, since this cintiq+art pen combo used to work fine.
My speculation right now is that the USB controller in the Cintiq is bad, and is falling back to some lower speed than it normally would. It would then be unable to send all the data the Art Pen is sending, resulting in low sample rate for some sensors, like pressure. This would explain why the eraser tip is OK - it has fewer sensors.
I don’t know this to be true, of course, but it would make sense at least. To back up a bit, this all started when I started getting random crashes on my PC - write errors on disks, segfaults, freezes etc. No systems tests I ran found anything wrong - memtest completed fine, the hard drives seemed OK, the crashing continued with a different GPU, so eventually I figured the motherboard must have gone. In the process of trying to figure this out I also reinstalled my OS a few times since the HD kept getting corrupted. That’s when I tried painting in KDE Neon and found this Wacom issue.
Now, having replaced the motherboard and CPU, the crashes are gone. But depending on the USB port I use I get USB errors from the Wacom. I’m wondering if it was the Cintiq all along… Maybe the old motherboard was more sensitive to whatever faulty data the Cintiq was sending out and that was causing the crashes. Or, maybe something fried the USB controller on the motherboard, and the Cintiq as well! Either option would explain the odd coincidence of crashes and the Cintiq failing at the same time.
BTW @Deevad I retested setting RawSample to 20 and I do notice a difference in the way the cursor responds - there’s noticeable lag, as you’d expect. It just doesn’t seem to average the pressure data. Maybe that’s intended, after all since the pressure data apparently is known to only get updated every n polling cycles, you couldn’t just average 4 samples together since some would have no data in them. Although it seems like a pretty simplistic approach if that’s what’s going on.
I have a Cintiq too but I am on a W10 system because all my tests on Linux gave poor results. I am if the opinion that the drivers are not good on Linux.
Do you want me to test something still?
No need, thanks. What kinds of issues did you get on Linux, though?
Well the pressure is cut to very few levels compared to what cintiq has. It felt like my old Bamboo. It is just the bare bones essencials for it to run. Having a Cintiq and having it run like a Bamboo is not appealing to me.
Also there were a lot of options missing. For me essential was the control of luminosity , contrast and temperature. I am an epileptic so if I can’t control my screen I will not be able to use it literally more than 1 minute. But there is a lot more missing than just that.
Connected to this was the fact that Linux dulled colours alot on lower contrasts and no windows scalling and graphics card issues did not help me stay. Don’t know how how neon is now though with that it was last year or so.
But everything related to the Cintiq as a screen and as a tablet does not work or works very poorly. So I stay on windows.
Ah, your Cintiq handles display settings via the driver? Mine is an older 24 HD touch, and it has physical buttons for all the settings. They’re very annoying to use, but they’re there.
Yes it is all with the drivers now 
I just have the power button physically. Even the top screen options are touch screen and driver powered I think. It is faster to use the app than to use those buttons.
Honestly I liked Neon more than the other Linux distro a but yeah 
Yes, controlling the luminosity/contrast and all option is done now only via a driver on Win/Mac (no physical button and OSD since… ~2015 and the 22HD era? ).
To control the Luminosity/Contrast on Linux; here is the only possibility I found: Cintiqs on GNU/Linux: How to setup brightness, contrast and more. - David Revoy
Interesting. Do the settings get saved on the Cintiq itself, or do the get applied by the driver every reboot? IOW if you set them once and , say, reinstall your OS, do the Cintiq settings stay set?
