This sounds like the known 'reuse front buffer' issue. It's a unofficial trick I use to limit redrawing to e.g. the editing area only, but not all drivers act like expected. Turning the 'reuse front buffer' option of in the main options (or using the graphics wizard in the statusbar) should fix it.
Although if it's only noticeably during the first couple of redraws, you might want to keep it enabled in favor of the increased rendering speed. Future versions might get a better way for recycling previous renderings, but those methods require higher OpenGL versions, although that seems to become less of an issue lately as a result of better gl support.
In the other thread you wrote you're on 64 bit Ubuntu, so the 32bit binairiy works without any additional steps on that? (chroot setup for example).
