> These little difference in values are seen both initial drawing and updates.
> These tests are not run from long time and change in product might change lod values.
> 
> With updated lod values i have verified that both the tests pass in OpenGL and Metal pipeline with both retina display(scale = 2) and external monitor(scale = 1).
