Screen shot showing behaviour.
For some reason the tabs for the sheets and scroll bars on both sides are being chopped off by the sheet being displayed.
This is on a Kubuntu 14.04 install with Oxygen fonts (forced to 96DPI) and QtCurve widget style.
I cannot confirm Debian Jessie/Sid with KDE 4.13 and LibreOffice 4.3.
I follow all releases of LibreOffice, did not see displayed behaviour. I attached screenshot of my desktop.
