It turns out that my earlier assumptions were wrong and this is entirely
down to EXA vs UXA. Using EXA in either jaunty's 2.6.3 or a 2.6.99
snapshot performs poorly, and switching either to UXA brings back
Intrepid smoothness (and other bugs such as occasional rendering
artifacts, hangs and segfaults on resume).
