Public bug reported:
Open a file that takes a lot of memory and/or is cpu-intensive to
render, such as a huge SVG file with a lot of stuff.
Zoom in so that the document is significantly bigger than the window
Compare these two cases:
1) (works as expected) Click somewhere and drag to somewhere else, to
move the document relative to the window
2) (BROKEN) Drag the vertical or horizontal scrollbar to scroll the
document vertically or horizontally
Expected: in both cases, after you're done moving, the program will take
its time to render the new visible portion of the document and when it's
done you'll see the document at the position where you have moved. The
distance the document should have moved should be exactly equal to the
distance the mouse cursor have moved while dragging.
Observed: case (1) works as expected. But in case 2, the scrollbar will
only move a very little bit and the document will only scroll a little
bit. The scrollbar won't ever reach the point where the mouse cursor is,
not even closely.
Scrollbars just can't be used to navigate in a document that is "costly"
to draw.
