When I upgraded to 2.68, the render result started tiling a certain section of the finished render.
it looks like this
but when the image is saved saved and viewed outside of blender, it is correct.
I think this may have something to do with my OS, as when I upgraded blender, I had to manually upgrade all of blender’s dependancies.
My OS is 64-bit Arch linux, completly up to date.
Any help with this would be much appreciated .
