Bug Description
Binary package hint: libreoffice
When I have word document opened in libreoffice for more than a day, after that time the scrolling of the scroll bar takes a minute to finish. Redrawing the screen seems to fail, in the sense that subsequent sentences are overlapping (showing only half of one of them)
I cannot produce a screenshot, because the process consumes more than 50% cpu. To describe what happens, imagine a scroll of half a page or so: it start the scroll, hampers on redrawing the bottom lines (when scrolling down), then finishes after about 10 seconds with >50% cpu activity. When it reaches its 'destination', it restarts from the beginning (top) and show the same behaviour several times.
I have this problem with a word .doc file and adding comments to text, but I do not know if this is related.
I have switched off the 'java' option in the preferences (having read about that solving the problem somewhere), but that doesn't help.
closing and reopening the document resolves the problem: fast response to scrolling the mouse.

I just noticed that the jumping up and down when scrolling, as described above (starting point to 'destination' and back), also occurs without the >50% cpu load: it is because the text cursor is still inside a comment in the word document. This restricts Libreoffice to leave that page somehow. The comment has to stay visually in the screen and you can scroll only sofar as the size of the comment "block" allows you.
The bug for >50% cpu load on scrolling still holds: it occurs after having the document open for >24h.
