[Blocking Requested - why for this release]:

This looks bad and it's a recent regression so nominating this to block.

Gaia is the same so it's a Gecko issue.

Thinker this issue seems to have been caused by the changes made for bug 1097464.  Can you please take a look?

Comment 5

[Thinker Li [:sinker]]

Could you take a video and attach it on the bug?

Comment 6

[Thinker Li [:sinker]]

ok! I have found the video.  I think this is the same problem as Bug 1206418.

Comment 7

[Bobby Chien]

Milan, could you help on this?

Comment 8

[Milan Sreckovic [:milan] (needinfo for best results)]

Seems to be a layout related issue, and Thinker's already got a patch on bug 1206418, so let's see if that works.

Comment 9

[Chris Lord [:cwiiis]]

This should now be fixed, qawanted to verify.

Looks like bug 1206418 has just landed today, so I used inbound builds to test this. Confirmed that this is fixed on latest mozilla inbound on Aries and Flame. Icon no longer flickers when moving them over another icon.
