Summary:
Refraction Weirdness with smooth/flat shading geometry-dependent
Detailed description
OOOOOOK, this is one of the strangest bugs I've seen
When refraction is on there are some wierd results on rendering, depending on geometry as can be seen by the shapes I use.
I've simplified the scene so that it can be better seen.
This wasn't there yesterday...Maybe has to do with the recent raytraced optimizations?

...And indeed a revert to 34655 does not have the bug.

Reflection is also broken since r34657.

Right, today's commit has an issue with non-flat quads that become traingles. Probably a simple fix for Brecht :)

Probably rendering results are correct, but the speed became much slower!! :(

Oh... sorry, my previous post was hasty conclusion... The speed didn't change.
