I have found what is, IMO, a bug with LibreOffice Writer.
My version is 220.127.116.11 and Build ID 40m0(Build:2). My O/S is 64-bit Ubuntu 15.04, Linux kernel 3.19.0-21-generic. I cannot tell if the problem occurs with other versions of LibreOffice and/or on other O/S'es.
The problem is pretty easy to describe and completely reproducible on my system.
Let’s say I am editing a large document (it can be ODT or Word format). I make some changes, and scroll to another part of that document (for example, 50+ pages away) preparing to make an edit, but not having clicked in the new location. Then Writer decides it is time to autosave before I can click to set the new insertion point. It autosaves and sends my view in the document back to where the insertion point is, some 50+ pages away from the point I have so carefully scrolled to.
I do not believe that autosave should do this, and I certainly cannot see any way to mitigate the problem. Increasing the autosave time will lessen the frequency but that is a trade-off against possible loss of more work if Writer should crash/hang and be unable to recover.
Problem already reported in bug 92365 which is a duplicate of bug 41063.
Best regards. JBF
