Mysterious 7MB memory leak in iOS?

    (using: Unity 5.6.3)

    I came across an unexplained phenomenon in our Unity-built iOS project: After the initial loading, the game would then slowly creep up memory usage (while nothing was happening) until it reached a certain point, 7MB higher than it started. I began disabling various startup systems at random until I decided to build a blank project and get a baseline. Lo and behold: the same memory leak, on a blank scene (see screenshot). Obviously the baseline memory usage was different but the increase is the same, 7MB.

    I can't be the only one who's seen this, right? Any explanations?

    I just checked, and this issue still exists in 2017.2 for blank projects.

    You tried 2017.3 beta just to see for curiosity?

    I don't have that installed (I did have 2017.2), and don't plan to install it just to test one bug, especially since the release notes don't mention anything about memory improvements.
