SUMMARY I am colouring comic book pages. When starting to colour a new page, it is useful to also have open an earlier page so that I can select a shade from the earlier page to use the same shade on the new page. Then selecting the colour I have been using the "Ctrl" key. However, on returning to the new page, I find that the cursor is jumping (approx. 10 pixel steps). This occurs only when I am using the brush tool. This does not occur if I use the Colour Selector Tool and does not appear to occur when using the "Ctrl" key with any other tool selected. Also, it only seems to occur when I am selecting colour from an earlier page in jpeg format. 


STEPS TO REPRODUCE
1. Start Krita and create a new document.
2. Open a second document in jpeg format.
3. Select Brush too (any brush).
4. Select a colour from the jpeg image. 
5. Draw on the new image. 

OBSERVED RESULT
Cursor moves in jumps and line drawn very slowly. (Note brush option set to "Normal").
