This problem started with a new version of LibreOffice, 18.104.22.168. (the one with the new green splash screen instead of the old white one) and continued up to the latest 4.x versions.
My documents are not displayed properly when I scroll up or down.
The problem appears only above a certain zoom level and is the same in odt or doc.
Example. Have pasted a text here
After scrolling down:
and then up:
Clicking on the text restores it but it always goes back to the beginning which is the only part that is visible in this way - and larger documents are almost unusable!
The document can be taken under control if the zoom is equal or lower than 180%. It may vary depending on display and resolution, but it seems to me that the problem disappears as soon as the zoom goes down so that the page is largely within the margins of the maximized window.
On my display the comfortable zoom level (the one that I would prefer to use, and cannot) would be 230% (e. g. with 11 Arial).
This also affects other parts of the office suite (Calc, Impress).
I never had display problems with this laptop before, and previous versions of Libreoffice worked ok.
I have tested with a live usb and the same LibreOffice version and the problem appears in the same manner.
This happened initially in Lubuntu 12.10, and then in Xubuntu 12.10 too, and in all versions of LibreOffice above 3.5.
I am able to use msoffice 2007 under Wine with no problem. To avoid the present issue, I use LibreOffice 3.5.
