Solved. It turns out that xserver-xorg-video-intel had become un-installed on my machine. I do not know how this happened, although apt-cache show says:
""" The use of this driver is discouraged if your hw is new enough (ca. 2007 and newer). You can try uninstalling this driver and let the server use it's [sic] builtin modesetting driver instead. """ I recently reinstalled to go to multiarch amd64 to try and squeeze some extra performance for video editing; perhaps the intel driver wasn't installed by default. My graphics controller is "VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)" and installing xserver-xorg-video-intel causes libreoffice to work well again with correctly rendered toolbars. I don't know why only libreoffice was compromised, but this bug can be closed as bogus/not belonging to this package. Thanks for your assistance, and for showing me interesting bits of the source code. Nick/.
