Description john@ridgwaydesign.fsnet.co.uk 2020-03-29 14:56:49 UTC 
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").


EXPECTED RESULT


SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
The "jumping" did not occur in the beta version.

Hi, I am going to need to see a short video to see what exactly you mean, because I cannot reproduce this here. Is this possible?

I am now unable to reproduce the jitter problem. I assure you that it was a
problem that occurred several times and I could only cure it by re-starting
Krita. I am sorry that I appear to have wasted your time.

Sincerely

John Ridgway.

Don't worry. Sometimes bugs just get fixed inbetween versions, without us needing a report because we notice something was off.
