Yeah, I can't reproduce this issue on other x86_64 machines running Sid,
I'm fairly certain its a rendering issue with a different package (not
sure which though) based on the other rendering issues occurring
(screenshot attached). Maybe it is an Intel Ironlake related bug? Not sure.

Nope, changing fonts then flipping pack immediately or within 5 to 10
minutes doesn't cause the issue to disappear, if I wait over 30 minutes
and change back the rendering errors stop for another few hours though.

Font size is set to 11, I'm unsure if LibreOffice is affected, will
check next time it occurs. Based off previous examples I'm betting the
menus that use Cantarell Regular in Libreoffice will be affected.
