--- Comment #2 from Stefan Brüns <stefan.bruens at rwth-aachen.de> ---
When I zoom in using Ctrl + Mouse Wheel Up, the page contents are magnified
immediately, but for a very short time the contents are "blocky". This is not
persistent, but the contents are immediately rerendered with the higher
resolution. This is the expected behaviour.

When I use a pinch zoom gesture, the last step - rerendering at current
resolution - is omitted.

As soon as I move the page around (cursor keys, mouse, touch), the contents are
rerendered.

I have tried to create two screenshots - the left half shows the jaggy edges
immediately after zooming, the right half after pressing cursor down.
