Hey! If it helps, I figured out a way to force my grid items to be pixel perfect (this was done via using a separate image for the items btw). After deciding how I big I wanted my grid menu to be, I checked what size the item icons were forced to be in the grid and simply made my separate image file that size (so my image files were 48x48, but it was forcing them to be 58x58 so I just made the canvas the correct size). Once I did that, my images kept their pixel perfect look.
It don't know if this will help you figure out the cause for the blurriness, but I figured I'd share at any rate!
