The automatically moving/increasing canvas is nice but it's a tad too aggressive, making it hard to use sometimes (try to position and especially resize and move big images for a minute and you see what I mean). Shows up esp with zoom-to-fit but with a small zoom level, moving images also shows weird flickering.

I think you can solve at least most of this by not resizing (at least not *shrinking*) the canvas when moving and resizing objects until it is done and maybe by having some 'extra space' always there.

Reproducible: Always

Steps to Reproduce:
1. Add a big image to a fit-page zoomed document.
2. Resize and move the image until it fits nicely on your document
3. Enjoy the flickering and hard-to-control movements.
Actual Results:  
The canvas flickers, object movements are hard to control.

Expected Results:  
Maybe no decreasing of the size of the canvas when moving objects, resize when done? I'm not sure if that'll solve the problem...
