On latest master flame-kk, tiles are rendered incorrectly during APZ.

[1] Open Browser app
[2] Move to
[3] Zoom page until font becomes very large.
[4] Shrink zoom some amount
[5] Scroll diagonally(relatively horizontal direction) on around top of the page several times.

[3] and [4] seems to important to reproduce the symptom.

Ok, so I flashed the latest mozilla-central on the flame and I am unable to reproduce what is shown on the video. However, sometimes I get incorrect content (wrong parts of the page) rendered in the low-res area when zooming out by a lot (but not every time, it seems to happen only when I have been messing up with the zoom for a long while).

I'll keep looking into this zooming business and hope that the issue you are experiencing is somewhat related.
