Strange downsampling issue / Graphical Effect in iRay

Hi,
I'm having some weird issues with specific areas of a texture. The issue only effects iRay.
There are certain areas of the texture that seem to bleed across additional pixels; specifically red part triangles. The rest of the texture behaves perfectly normally. I've applied the texture to a primitive plan and observed the same effect. Its alomost like the renderer is downsampling the red areas.
Any thoughts, have I stumbled on a bug or am I doing something stupid...
Thanks

Iray does compress images over certain sizes - the thresholds are set in the Advanced tab of Render Settings
