Details

In the settings up when scrolling up/down the content becomes stretched and occasional returns to normal. I changed gecko to use 3 as pixels/css pixel (bug 961505). This might be a rounding problem. The stretching is only in y direction afaict. Occasionally the scrolled content also goes blank (black) so this might be also a driver issue around large textures.
This disappears when I turn on tiling. I assume that we are hitting some driver problems with huge textures (the nexus 5 is 1920 x 1080. We might be over-sizing the display port beyond the texture size or something.
I tried clamping the displayport to smaller values, even ones smaller than the screen itself, and the problems here persisted. I also tried turning on tiling and the problems went away for me too. I didn't experience any stretching artifacts, though. I noticed content going black, and what seemed like content being painted over an old buffer. I don't have a working theory at this point, but I'll look more into it.
Also, adb logcat provides literally no information.

This sounds like it was filed for B2G initially. And is no longer an issue.
