Huge bug: Pencil won't work properly, creates tons of extra lines. PLEASE HELP!

So, I just got Pencil2D, I’m super new to it.
But the moment I try to draw on the canvas, the line I create is accompanied by dozens of lines lagging slowly behind it in an array, and when I take my pen off, it STILL keeps going, making random lines and spazzing out.

-Mouse works fine: doesn’t have this problem
-I tried deleting and re-intstalling and updating Wacom driver

@GlaucousLace Hi. Sorry to see you’re having issues and thank you for being so thorough with your report, it helps a lot.

It is quite odd indeed that this is happening since wacom tablets are about the most compatible input devices with Pencil2D, but there’s always a first time I suppose.

Anyway, can you please answer a few more questions to help developers review this faster?

  1. Which version of Pencil2D are you currently using? To find out go to HELP > ABOUT menu.
  2. You mentioned you’re using a mac but which version? To find out follow this guide https://support.apple.com/en-us/HT201260
  3. If possible can you let us know what is the wacom tablet product number (e.g PTH-450) which you can find on the back of the tablet itself or in the box
  4. And what is the driver version you downloaded? e.g 6.3.19-3

If you updated the drivers to the latest web version for your tablet, you’re certainly a step ahead, however I have to ask that you try to use other drawing software to report if it’s a global issue with the tablet or if it’s specific to Pencil2D under macOS environments?

You can try the following free drawing apps to see how the tablet behaves:

If any of those work properly, then we’ll take a deeper look into this issue. For now i’ll tag one of the mac developers so they can guide you further once you’ve provided the info I mentioned, but just in case you require to work and you can’t wait for Pencil2D to get fixed while you’re being provided with customer support, please take a look at our curated list to find another animation software that can help you meanwhile:

Hopefully this can be solved soon for you.

@scribblemaniac Hey sorry to bother you. I was wondering if you could take a look at this issue once the user has submitted the pending details I asked recently. It seems like a non-standard problem and it is mac related so I thought you’d be better equipped to review it, once we ascertain that it is a reproducible bug. Thanks in advance :slight_smile:

Thank you for such quick help!

The version I have installed is ‘0.6.4’
My mac operating system is OS X El Capitan (10.11)
my Wacom tablet product number is PTH-651
and finally my driver is 6.3.35-2
(Another point of note is I had the previous driver version after I downloaded and installed Pencil2D when I discovered the issue. I checked for driver updates and installed the update hoping it’d solve the problem, but it still persists. my computer is also fully updated)

I’m an artist and draw quite often using clip studio paint and photoshop and flash, and I’ve never run into this bizarre an issue before, I just did a check just in case and it currently works perfectly fine on all my drawing software ^^

Also a couple maybe useful things I forgot to mention in my original post but might as well provide in case they prove useful!
-Tried the ol’ “turn computer off and back on again/restart” trick to no avail
-Tried turning mouse off whiles using tablet in case it was like sensing the mouse as well or something weird, but no luck
-Tried turning of pressure on Pencil2D and fiddled with sensitivity/pressure/touch pad settings on my wacom to try and fix or at least help or worsen problem in hopes of finding it’s source, but alas stayed just as crazy glitchy no matter what
-This glitchy weirdness applies to ALL tools, not just pencil. The only tools exhibiting normal behavior are non-drawing based tools like select and fill bucket etc. etc. Even smudge tool is doing the weird line spazziness

Again, thank you so so much for the kindness and help and so quick!! Hopefully it’ll be running smooth in no time.

Well you’ve done almost everything I would suggest already. There are a few things I can think of for you to do right now that might help. First off, make sure you are using the new legacy mac build. On the Pencil2D downloads page, under the Mac panel, make sure you’ve downloaded the 10.7-10.11 version rather than to 10.12 version. If you are already using that version, then you can try and use the 10.12+, it might still work for you. Second, if you could record a video of the behavior happening that would be really helpful to visualize how the extra lines are being drawn. I would recommend using either the builtin Quicktime Player or the free and open source licecap to capture the screen. Finally, if you can, please try downloading Krita which @JoseMoreno linked above and seeing if it has the same problem. Unlike clip studio paint, photoshop, or flash, it uses the same programming framework as us, so this would help to narrow down if it’s a problem with Pencil2D or this framework we use.

Sure thing! Where would you like me to send the video to for you? And I’ve got the right version all checked and set up. I’ve got Krita downloading so I’ll tell you the results of that when I get em.

@GlaucousLace You can upload the video on youtube.com or anonymously on streamable.com and paste a link here :slight_smile:

Here you go!
