Comment 1 for bug 1668274

AFAICT the selected object which was dragged when the move was canceled by opening the canvas context menu is temporarily rendered at the size it has at 100% zoom level - despite the canvas e.g. being zoomed out to 50% - and at the position offset relative to the page origin (bottom-left page corner) instead of the SVG origin (top-left page corner) at 100% (again ignoring current canvas zoom level).

This can be tested easiest in a px-based document, but exposes the same way in a new default mm-based document.

This incorrect temporary rendering (the correct appearance is restored when changing the zoom level, or toggling the current layer's visibility) is a regression in >= 0.92. The fact that opening the canvas context menu during an on-going drag operation (moving a selected object with the mouse) cancels the drag operation is reproducible e.g. with 0.47, 0.48.5 and 0.91 as well.

Based on tests with archived builds (on OS X 10.7.5), this temporarily incorrect rendering is:
- not reproduced with 0.47, 0.48.x, 0.91
- not reproduced with lp:inkscape rev <= 14831,
- reproduced with lp:inkscape rev >= 14835,
- reproduced with 0.92.0, 0.92.1, lp:inkscape/0.92.x r15394
the reported rendering regression was likely exposed with the canvas refactoring/ attempts to fix "invalid state when picking" messages during the hackfest 2016:
