Summary: thin white primitive borders are shown despite texture

Initial Comment:
Sometimes, depending on their size and/or position, rectangles (and I guess other polygons too but I mainly work with rectangles) are shown with a thin white border even if they are textured with a pix that has no white pixel in the proximity of the border, e.g. a completely black image or an image whose pixels close to the border are all black or transparent.

This has been there for years, I've always seen this happen since I use gem, across many versions. This happens both with Linux and Windows, i don't know on Mac OS.

If a rectangle is moving or changing size, the borders appear and disappear. Most of the time they are absent, I mean the values of position and size that cause the borders to appear are just a small fraction of the total.
