  • Bug Continuous scrolling jumps at the start or end of a page

    When "Page display" is set to "continuous," I expect the scroll smoothly from one page to the next. This does not happen.
    Instead, I find this: as I go down the page, I see the gap indicating the end of the page. If I scroll one bit more, the display jumps so that the top of the screen is now the top of the page. In order to see the gap between the pages (to confirm that's where I left off), I have to scroll back up a ways. This happens when using both the mouse or the down arrow key. It does not happen with PgDn key.

    That's bad enough, but it gets worse when scrolling upwards. Again, as I scroll up, I see the gap indicating the start of the page. If I scroll one bit more, the display jumps to the top of the previous page. That's right: not the bottom of that page, but all the way to the TOP of the previous page. That's definitely NOT continuous! Again, this happens both with the mouse and the up arrow key.

    Very annoying!

    Sorry for the delay in reply. Do you use 'fit visible' option when trying to continuous scrolling? If this, we are aware of this bug, and have reported to our team for further investigation.
    Any update, we will keep you informed.

      I have the same issue, and I use "fit width" option. What option is recommended?

        Bruce Fraser shmu26 ,We only could replicate the scrolling issue under 'fit visible' page scaling mode. For the issue "update to 9.4 broke continuous scrolling under 'fit visible' mode" (Report ID is QCPHANTOM-14842 in our internal system) will be rectified in our next minor release version V9.5 if everything goes well.
        shmu26 ,However,you said that you have such issue with "Fit Wdith" mode which is not the same to the problem that we have reported,so we still need your help to send us the following information for further analysis:
        1:Your OS information(eg:mine is windows 10x64bit)
        2: Did this issue happen to all PDF files or just some sepcific PDF files?
        3:Please send us one PDF file sample in which the issue could be replicated there.
        4:If possible, you may use the LiceCap tool to generate an animated gif that shows how to reproduce the problem for our referencing.
        Here's the download link:

        (Unzip it, then double-click on licecap file, you can then specify the recording area then hit "Record", it requires naming the file first then start recording.)

        If it is inconvenience to upload the files here, you may email it to [email protected] (Attn:Lisa). And indicate this thread link. Thank you.

          Sorry, I just realized I've made two posts about the same issue,
          And now I can't get the issue to happen!
          If/when it happens again, I will make careful note of which file(s) have the problem.
