Has anyone experienced major precision issues with the reprojection cache?

I'm currently caching indirect lighting computations temporally, and going from screen->world->screen always gives me some minuscule precision issues in xy (+0.0001 ish in pixel coordinates). I tested this precision issue by leaving the scene alone and not moving the camera. In this situation, using 100% of the cached values causes the rendered image to float right/bottom.

Have people experienced this before? If so, how did you mitigate it?
