Comment 5 for bug 1649870

I do see a difference between the browser display and the display in Inkscape if I follow your step-by-step instructions. It's not as pronounced as in your case, but different nonetheless.

The difference in display is also still there in Inkscape 0.92r15210. In Chromium, it looks the same as in Firefox. Creating a new layer (to circumvent the layer transform bug) does not make a difference.

But: it looks correct if the transform on the group is removed, by removing the mask, ungrouping after page size change, then regroup and remask.

In Inkscape 0.92pre, if I *create* an image like that there, it seems to work alright, although I only tested with two different sets of objects.
