I updated xserver to master branch along with the requisite x11proto-dri2-dev 2.1 and x11proto-input-dev 1.9.99.6 and there isn't an offset menu rendering problem anymore using the static mesa version on the blender website. The ubuntu repo version and static python version from blender.org doesn't show dropdown menus though leading me to think it's a mesa bug in 7.6 left still.
