tries to refresh the page view. Sometimes this can result in an infinite resize loop. Okular<br />
fixes this by resizing the content area to the new viewport size. As a consequence both horizontal<br />
and vertical scroll range become zero. Now if "Auto Fit" turns out to be "Fit Page" then it is fine<br />
but in case of "Fit Width" or "Fit Height", where one scroll range should be non-zero, both scroll<br />
bar disappear resulting in a view which appears to be frozen. So to fix this add scroll range<br />
to the dimension for which the scroll bar should be visible and then resize. Since the scroll range<br />
remains constant, an infinite resize loop won't occur.</p>
