The layouts at 100% or lower look ok, but my guess is they are set at the screen resolution of ~72dpi, which results in grainy looking images when you zoom in. Since on modern computers with high-resolution displays its almost required to keep the layouts at 200% or larger, it would be nice to have Igor render them at higher resolutions when zoomed in so they don't appear grainy. Granted one could always embed objects to make them appear smoother, but it would be nicer to just have layouts display objects in higher resolution.
