I'm not sure if this classifies as a bug or what, but the pixel perfect scaling option has been inaccurate to what I've been providing.
Here is an example of an image that I am using for a project, and here is what is looks like with the zoom set to the "1:1 Pixel Perfect Scaling" option within the program. For the most part the image looks fine save for some errant regions of pixels which I have no means of mitigating the effect of. Sprites look fine at 2:1 scaling and beyond, but lower than 1:1 is not preferable as it produces unfavorable results.
