yes, sorry. it's pretty mean to just discuss around the OP :-)

the bug most likely derives from the introduction of a shader based lanczos
scaling that was recently introduced.
apparently your GPU/driver is buggy on this.

unfortunately atm.* the activation (if you've shader support) is controlled by
the global eye-candy setting which is as well obscure as not too fine grained
(you'd probably loose various animations and quality settings that work ok on
your system)

the smooth scaling setting as it is, only controls a quality parameter when
using the xrender backend, thus my suggestion in #2 was to release it from the
backend and bind it to the lanczos filter on the opengl backend

*was too late in the release cycle
