Description dimitrisax 2015-11-20 20:20:51 UTC 
While  drawing quick, a lot of the strokes happens in wrong place.
eg I draw quick 5 centimeter long strokes on the same place and suddenly a random stroke hapens about 5 centimeters away from the place i draw them(on the same imaginative line). also if i stop drawing exactly when the wrong stroke occurs, the brush indicator maintains the deflection until i touch the stylus on tablet again.
this never happens in other software (i tested on gimp and mypaint)
!! this also happens in windows 7 with the original tablet diver !!
(in ubuntu i use the digimend huion driver)


Reproducible: Always

Steps to Reproduce:
1.open any file in krita
2.draw quick lines with the stylus
3.strokes

Actual Results:  
wrong mapped strokes


here are the tablet log when the bug occured, and the command outputs

https://paste.kde.org/puabumjwf (lsmod output)

Hey dmitri, thanks for going through the bother.

I am reuploading the tablet log as an attachment so we don't lose the information(paste only pastes up to a week or so)

Hi, Dmitry!

Do I understand it right that the offset was bigger than 7-8 pixels? And could you tell me, did you use any assistants or smoothing during these tests?
Comment 3 dimitrisax 2015-11-23 15:18:30 UTC 
Hi, again. Yes, the offset depends on how long the previous  stroke was. The longer the lines the more distant the offset. it happens usually on bigger files, and a lot more when firefox is open. my pc is not great but this happens only in krita unfortunately. Even with no assistants or smoothing it keeps doing it. it happens also when autosaving

Does this still happen with Krita 3.0?
