(I know Inkscape has a lot more features, but just loading one image + adding text on top should not lag a 2 GHz Quad-Core / 8GB machine.)
I use Sketch, and I highly recommend it.
If you are dealing with big bitmaps (eg. 108 megapixels of s20 ultra at 24 bits per pixel requires at least 324 of MB of memory if it was encoded without any metadata, but I am sure even bitmap processing software like Photoshop will multiply that by a large factor, let alone vector image editors). Full A4 page scan at 600dpi is ~35 megapixels and at 1200dpi 140 megapixels.
Sure, we can easily think of ways to optimize this (eg only load a preview image for the current zoom level, and when changing zoom level, take the online map tile zooming approach and load in the background), but when dev resources are scarce, you focus on your core competence (vector editing with Inkscape).
