Bug was probably due to an improper driver upgrade, thank you for your help. As
obvious as it may sound I had not tried uninstalling and reinstalling the
driver, because I thought the fault couldn't possibly come from it as every
other program (including FireAlpaca, Photoshop, Paint and Sketchpad) were
working perfectly fine.

Thank you for your time !

I literally just tried the same model CTH-480 with the same driver version
6.3.25-5 and there aren't any issues.

I suggest you reset the Wacom driver configuration completely with the Wacom
Tablet Preference File Utility, make sure no remnants of possibly broken
configurations are in place, uninstall the driver completely and install it
again (_not_ simply reinstalling). If this doesn't change anything, I'm afraid
there is something seriously wrong with your system that we can't fix here.

Driver is updated to version 6.3.25-5 which should be the latest
The problem happens whatever Krita's pointer API is set to and whether or not
windows ink is on.
Despite the log showing the driver malfunctioning, I must mention that
photoshop on the exact same machine does not experience this issue at all and
draws smooth lines from the get go.

Well, it's obvious from the log that the driver sends several move events with
the same coordinates but varying pressure, then sends more move events with a
big jump.

I'm feeling a bit dumb for not asking these earlier...

- Are you using the latest Wacom driver?
- Which version is it?
- Does it happen if you disable Windows Ink in the Wacom settings?
- Does it happen if you enable Windows Ink in the Wacom settings and change the
tablet API in Krita to Windows pointer input? (You need to restart Krita for
the changes to apply.)
- Does it really also happen with the mouse like you mentioned in the OP?

Can you make a tablet log by following this?
https://docs.krita.org/KritaFAQ#What_if_your_tablet_is_not_recognized_by_Krita.3F

Draw a few circles while making the log. Try to make at least one fast stroke
and one slow stroke. Please also take a screenshot of the result so we can
correlate the tablet log with the strokes drawn on the canvas.

I have added the information ! I have an Intuos Pen and Touch small ( CTH-480 )
I have added system information to a separate comment.

I know it doesn't change that much but it has fixed some lag issues for me in
the past so that was one of the first fixes that came to mind. But thanks for
the tip !

100% RAM was only to test if that was the problem ! Instant preview does not
change anything, and I have no smoothing mode enabled on the brush

What tablet device are you using?

Also, please provide the info from Krita "Help"->"Show system information for
bug reports".

(Protip: Setting a process's priority to realtime does not do what you think it
does. On Windows, mouse input doesn't even run as high as realtime priority, so
if a realtime process ends up using 100% CPU you won't even be able to use the

I am not sure if 100% ram is really wise, but I believe that is seperate from
