Description Mykola Franchuk 2017-02-17 01:02:52 UTC

Canvas moves randomly on the screen.

Reproducible: Always

Steps to Reproduce:
1. Rotate canvas more than 60 degrees (plus or minus). The larger angle of the canvas rotation corresponds to bigger shakes.
2. Use pan tool ONLY from the panel (middle mouse button works well) to move canvas.
3. Look at shaky canvas.

Alright, so this problem is only with the tool from the toolbox? I'll specify that in the title, because that code is slightly different from the middle-mouse button.

I can reproduce this issue.

This is now fixed in master, which I assume is due to Victor Wåhlström's patch ( https://phabricator.kde.org/D6245 ).
