When the user is viewing an image in gallery and rotates their phone (portrait-to-landscape & vice-versa), they will observe that the photo has a smooth transition between these views. However, when the user is in 'Edit Mode' and performs the same manuevers, the image will flicker and sometimes 'jump' from a different draw to it's actual position.

* images in gallery
Repro Steps:
1) Update a Flame to 20150409010203
2) Open Gallery
3) Tap an image
4) Rotate phone portrait to landscape
5) Observe transition fluency [Expected]
6) Enter edit mode (gallery + pen icon)
7) Repeat 4 + 5 [Actual]

Image will flicker and draw incorrectly, flash to actual position

Image transitions smoothly with rotation

For some reason, I was seeing this for a while too, thought I raised this bug as 2.2 blocker, but apparently I was mistaken.  The closest bug that I raised is https://bugzilla.mozilla.org/show_bug.cgi?id=1137445.  Perhaps it has same underlying issue.  Kats, is there anything else we can do to find out more?  Also.  Bug 1137445 was nomed for 3.0? for a while.  Do you think that bug and this one can be a 2.2 blocker?

Given that both bugs are not regressions in 2.2 they likely won't be accepted as blockers for 2.2. I don't know if we can say they have the same underlying cause without further investigation.
