After updating to the newest update, I have noticed some of the picture new size calculation is off. The actual size created is correct but this issue makes me double-check everything to make sure the size is correct.
You can see an example in the screenshot where an image upscaled to 2048x2048 shows a size a mere kilobytes when it is actually a few megabytes.
While not a bug the export again button is an annoyance as it used to be the close button and my muscle memory keeps hitting it.
