Description Tom Hall 2012-07-28 17:57:21 UTC 
Using the new interaction system in canvas-only mode, zooming causes the canvas to jump to a different position unless the canvas is centred on the screen.

Reproducible: Always

Steps to Reproduce:
1. Enter canvas-only mode (Tab)
2. Middle click and drag to offset the canvas slightly
3. Control + middle click and drag to zoom in/out
Actual Results:  
When you try to zoom, the canvas jumps so that its top left corner is in the centre of the screen.

Expected Results:  
Canvas stays where it is and zooms.

It doesn't appear matter whether the canvas is offset before or after entering canvas-only mode.

Yes, I can reproduce this. Of course, we also have other bugs with jumping canvases and zooming.
Comment 2 Halla Rempt 2012-08-08 18:45:49 UTC 
Marked as regression.
Comment 3 Dmitry Kazakov 2012-09-14 10:57:31 UTC 
Fixed after merging my zoom-pan-testing branch
