Comment 2 for bug 1462314

Please add information about OS/platform and Inkscape version to the bug description, thank you.

AFAICT the result of ungrouping is to be expected based on the SVG structure of the drawing (a huge rectangular path with a page-sized bitmap pattern fill, wrapped in a group which is clipped to the page size. On ungrouping, you delete (release) the clip, and thus reveal the unclipped pattern-filled rectangular path (its size exceeds the max zoom level of inkscape; the pattern fill repeats endlessly, and fills the visible portion of the rectangle).

Could you provide details about the origins of the drawing content in your attached Inkscape SVG file?
