Is this not a gaia issue?

Comment 2

Not sure..
change to gaia and leave someone to confirm it

Comment 3

It appears that only the text overlays - not the photo. This might be a graphics invalidation issue. Cjones, is there a way to diagnose these?

[Matt Woodrow (:mattwoodrow)]

Can someone please follow the instructions in comment 4 to diagnose why this is happening.

I'll take this if it's an actual gecko invalidation bug.

Matt, I'm 99% sure this is (yet another) symptom of bug 799644, which is a shadow-layers bug.

Lawrence and I just tried to reproduce and can't with the 2012-10-24 build on an Unagi.  Please re-open if it's still an issue.
